Waco (/ˈweɪkoʊ/ WAY-koh) is a city in and the county seat of McLennan County, Texas, United States. It is situated along the Brazos River and I-35, halfway between Dallas and Austin. The city had a U.S. census estimated 2023 population of 144,816, making it the 24th-most populous city in the state. The Waco metropolitan statistical area consists of McLennan, Falls and Bosque counties, which had a 2020 population of 295,782. Bosque County was added to the Waco MSA in 2023. The 2023 U.S. census population estimate for the Waco metropolitan area was 304,865 residents.

Indigenous peoples occupied areas along the river for thousands of years. In historic times, the area of present-day Waco was occupied by the Wichita Indian tribe known as the "Waco" (Spanish: Hueco or Huaco).

In 1824, Thomas M. Duke was sent to explore the area after violence erupted between the Waco people and the European settlers. His report to Stephen F. Austin, described the Waco village:

This town is situated on the West Bank of the river. They have a spring almost as cold as ice itself. All we want is some Brandy and Sugar to have Ice Toddy. They have about 400 acres (1.6 km2) planted in corn, beans, pumpkins, and melons and that tended in good order. I think they cannot raise more than One Hundred Warriors.

After further violence, Austin halted an attempt to destroy their village in retaliation. In 1825, he made a treaty with them. The Waco were eventually pushed out of the region, settling north near present-day Fort Worth. In 1872, they were moved onto a reservation in Oklahoma with other Wichita tribes. In 1902, the Waco received allotments of land and became official US citizens. Neil McLennan settled in an area near the South Bosque River in 1838. Jacob De Cordova bought McLennan's property and hired a former Texas Ranger and surveyor named George B. Erath to inspect the area. In 1849, Erath designed the first block of the city. Property owners wanted to name the city Lamartine, but Erath convinced them to name the area Waco Village, after the Indians who had lived there. In March 1849, Shapley Prince Ross, the father of future Governor Lawrence Sullivan Ross, built the first house in Waco, a double-log cabin, on a bluff overlooking the springs. His daughter Kate was the first settler child born in Waco. Because of this, Ross is considered to have been the founder of Waco, Texas.

In 1866, Waco's leading citizens embarked on an ambitious project to build the first bridge to span the wide Brazos River. They formed the Waco Bridge Company to build the 475-foot (145 m) brick Waco Suspension Bridge, which was completed in 1870. The company commissioned a firm owned by John Augustus Roebling in Trenton, New Jersey, to supply the bridge's cables and steelwork and contracted with Mr. Thomas M. Griffith, a civil engineer based in New York, for the supervisory engineering work. The economic effects of the Waco bridge were immediate and large. The cowboys and cattle-herds following the Chisholm Trail north, crossed the Brazos River at Waco. Some chose to pay the Suspension Bridge toll, while others floated their herds down the river. The population of Waco grew rapidly, as immigrants now had a safe crossing for their horse-drawn carriages and wagons. Since 1971, the bridge has been open only to pedestrian traffic and is in the National Register of Historic Places.

Waco was the original intended western terminus of the Texas and St. Louis Railway, with the town having been reached in 1881. However, the line was extended further west to Gatesville a year later. This trackage later became the core of the St. Louis Southwestern Railway Company, commonly known as the Cotton Belt.

In the late 19th century, a red-light district called the "Reservation" grew up in Waco, and prostitution was regulated by the city. The Reservation was suppressed in the early 20th century. In 1885, the soft drink Dr Pepper was invented in Waco at Morrison's Old Corner Drug Store.

In 1845, Baylor University was founded in Independence, Texas. It moved to Waco in 1886 and merged with Waco University, becoming an integral part of the city. The university's Strecker Museum was also the oldest continuously operating museum in the state until it closed in 2003, and the collections moved to the new Mayborn Museum Complex. In 1873, AddRan College was founded by brothers Addison and Randolph Clark in Fort Worth. The school moved to Waco in 1895, changing its name to Add-Ran Christian University and taking up residence in the empty buildings of Waco Female College. Add-Ran changed its name to Texas Christian University in 1902 and left Waco after the school's main building burned down in 1910. TCU was offered a 50-acre (200,000 m2) campus and $200,000 by the city of Fort Worth to relocate there.

Racial segregation was common in Waco. For example, Greenwood Cemetery was established in the 1870s as a segregated burial place. Black graves were divided from white ones by a fence which remained standing until 2016.

In the 1890s, William Cowper Brann published the highly successful Iconoclast newspaper in Waco. One of his targets was Baylor University. Brann revealed Baylor officials had been trafficking South American children recruited by missionaries and making house-servants out of them. Brann was shot in the back by Tom Davis, a Baylor supporter. Brann then wheeled, drew his pistol, and killed Davis. Brann was helped home by his friends, and died there of his wounds.

In 1894, the first Cotton Palace fair and exhibition center was built to reflect the dominant contribution of the agricultural cotton industry in the region. Since the end of the Civil War, cotton had been cultivated in the Brazos and Bosque valleys, and Waco had become known nationwide as a top producer. Over the next 23 years, the annual exposition would welcome over eight million attendees. The opulent building which housed the month-long exhibition was destroyed by fire and rebuilt in 1910. In 1931, the exposition fell prey to the Great Depression, and the building was torn down. However, the annual Cotton Palace Pageant continues, hosted in late April in conjunction with the Brazos River Festival.

On September 15, 1896, "The Crash" took place about 15 miles (24 km) north of Waco. "The Crash at Crush" was a publicity stunt done by the Missouri–Kansas–Texas Railroad company (known as M-K-T or "Katy"), featuring two locomotives intentionally set to a head-on collision. Meant to be a family fun event with food, games, and entertainment, the Crash turned deadly when both boilers exploded simultaneously, sending metal flying in the air. Three people died and dozens were injured.

An African American man named Sank Majors was hanged from the Washington Avenue Bridge by a white mob in 1905. Another man, Jim Lawyer, was attacked with a whip because he objected to the lynching. In both cases the mob was assisted by Texas Rangers.

In 1916, a Black teenager named Jesse Washington was tortured, mutilated, and burned to death in the town square by a mob that seized him from the courthouse, where he had been convicted of murdering a white woman, to which he confessed. About 15,000 spectators, mostly citizens of Waco, were present. The commonly named Waco Horror drew international condemnation and became the cause célèbre of the nascent NAACP's anti-lynching campaign. In 2006, the Waco City Council officially condemned the lynching, which took place without opposition from local political or judicial leaders; the mayor and chief of police were spectators. On the centenary of the lynching, May 15, 2016, the mayor apologized in a ceremony to some of Washington's descendants. A historical marker is being erected.

In the 1920s, despite the popularity of the Ku Klux Klan and high numbers of lynchings throughout Texas, Waco's authorities attempted to respond to the NAACP's campaign and institute more protections for African Americans or others threatened with mob violence and lynching. On May 26, 1922, Jesse Thomas was shot, his body dragged down Franklin street by a crowd some 6,000 strong and the corpse then burned in the public square behind city hall. In 1923, Waco's sheriff Leslie Stegall protected Roy Mitchell, an African American coerced into confessing to multiple murders, from mob lynching. Mitchell was the last Texan to be publicly executed in Texas, and also the last to be hanged before the introduction of the electric chair. In the same year, the Texas Legislature created the Tenth Civil Court of Appeals and placed it in Waco; it is now known as the 10th Court of Appeals.

In 1937, Grover C. Thomsen and R. H. Roark created a soft-drink called "Sun Tang Red Cream Soda". This would become known as the soft drink Big Red.

On May 5, 1942, Waco Army Air Field opened as a basic pilot training school, and on June 10, 1949, the name was changed to Connally Air Force Base in memory of Col. James T. Connally, a local pilot killed in Japan in 1945. The name changed again in 1951 to the James Connally Air Force Base. The base closed in May 1966 and is now the location of Texas State Technical College, formerly Texas State Technical Institute, since 1965. The airfield is still in operation, now known as TSTC Waco Airport, and was used by Air Force One when former US President George W. Bush visited his Prairie Chapel Ranch, also known as the Western White House, in Crawford, Texas.

In 1951, Harold Goodman founded the American Income Life Insurance Company.

On May 11, 1953, a violent F5 tornado hit downtown Waco, killing 114. As of 2011, it remains the 11th-deadliest tornado in U.S. history and tied for the deadliest in Texas state history. It was the first tornado tracked by radar and helped spur the creation of a nationwide storm surveillance system. A granite monument featuring the names of those killed was placed downtown in 2004.

In 1964, the Texas Department of Public Safety designated Waco as the site for the state-designated official museum of the legendary Texas Rangers law enforcement agency founded in 1823. In 1976, it was further designated the official Hall of Fame for the Rangers and renamed the Texas Ranger Hall of Fame and Museum. Renovations by the Waco government earned this building green status, the first Waco government-led project of its nature. The construction project has fallen under scrutiny for expanding the building over unmarked human graves.

In 1978, bones were discovered emerging from the mud at the confluence of the Brazos and Bosque Rivers. Excavations revealed the bones were 68,000 years old and belonged to a species of mammoth. Eventually, the remains of at least 24 mammoths, one camel, and one large cat were found at the site, making it one of the largest findings of its kind. Scholars have puzzled over why such a large herd had been killed at once. The bones are on display at the Waco Mammoth National Monument, part of the National Park Service.

On February 28, 1993, a shootout occurred in which six Branch Davidians and four agents of the United States Bureau of Alcohol, Tobacco, and Firearms died. After 51 days, on April 19, 1993, the standoff ended when the Branch Davidians' facility, referred to as Mt. Carmel, was set ablaze, thirteen miles from Waco. 74 people, including leader David Koresh, died in the blaze.

During the presidency of George W. Bush, Waco was the home to the White House Press Center. The press center provided briefing and office facilities for the press corps whenever Bush visited his "Western White House" Prairie Chapel Ranch near Crawford, about 25 miles (40 km) northwest of Waco.

On May 17, 2015, a violent dispute among rival biker gangs broke out at Twin Peaks restaurant. The Waco police intervened, with nine dead and 18 injured in the incident. More than 170 were arrested. No bystanders, Twin Peak employees, or officers were killed. This was the most high-profile criminal incident since the Waco siege, and the deadliest shootout in the city's history.

According to the United States Census Bureau, the city has an area of 95.5 square miles (247 km2), of which 84.2 square miles (218 km2) is land and 11.3 square miles (29 km2) is covered by water. The total area is 11.85% water.

Downtown Waco is relatively small when compared to other larger Texas cities, such as Houston, Dallas, San Antonio, or even Fort Worth, El Paso, or Austin. The 22-story ALICO Building, completed in 1910, is the tallest building in Waco.

Waco experiences a humid subtropical climate (Köppen climate classification Cfa), characterized by hot summers and generally mild winters. Some 90 Â°F (32 Â°C) temperatures have been observed in every month of the year. The record low temperature is −5 Â°F (−21 Â°C), set on January 31, 1949; the record high temperature is 114 Â°F (46 Â°C), set on July 23, 2018.

Previous professional sports franchises in Waco have proven unsuccessful. The Waco Marshals of the National Indoor Football League lasted less than two months amidst a midseason ownership change in 2004. (The team became the beleaguered Cincinnati Marshals the following year.) The Waco Wizards of the now-defunct Western Professional Hockey League fared better, lasting into a fourth season before folding in 2000. Both teams played at the Heart O' Texas Coliseum, one of Waco's largest entertainment and sports venues.

The Southern Indoor Football League announced that Waco was an expansion market for the 2010 season. It was rumored they would play in the Heart O' Texas Coliseum. However, the league broke up into three separate leagues, and subsequently, a team did not come to Waco in any of the new leagues.

Professional baseball first came to Waco in 1889 with the formation of the Waco Tigers, a member of the Texas League. The Tigers were renamed the Navigators in 1905, and later the Steers. In 1920, the team was sold to Wichita Falls. In 1923, a new franchise called the Indians was formed and became a member of the Class D level Texas Association. In 1925, Waco rejoined the Texas League with the formation of the Waco Cubs.

On June 20, 1930, the first night game in Texas League history was played at Katy Park in Waco. The lights were donated by Waco resident Charles Redding Turner, who owned a local farm team for recruits to the Chicago Cubs.

On the night of August 6, 1930, baseball history was made at Katy Park: in the eighth inning of a night game against Beaumont, Waco left fielder Gene Rye became the only player in the history of professional baseball to hit three home runs in one inning.

The last year Waco had a team in the Texas League was 1930, but fielded some strong semipro teams in the 1930s and early 1940s. During the World War II years of 1943–1945, the powerful Waco Army Air Field team was probably the best in the state; many major leaguers played for the team, and it was managed by big-league catcher Birdie Tebbetts.

In 1947, the Class B level Big State League was organized with Waco as a member called the Waco Dons.

In 1948, A.H. Kirksey, owner of Katy Park, persuaded the Pittsburgh Pirates club to take over the Waco operation, and the nickname was changed to Pirates. The Pirates vaulted into third place in 1948. They dropped a notch to fourth in 1949, but prevailed in the playoffs to win the league championship. The Pirates then tumbled into the second division, bottoming out with a dreadful 29–118, 0.197 club in 1952. This mark ranks as one of the 10 worst marks of any 20th-century full-season team. When the tornado struck in 1953, it destroyed the park. The team relocated to Longview to finish the season and finished a respectable third with a 77–68 record.

Waco has many golf clubs and courses, including Cottonwood Creek Golf Course.

In 2018, Bicycle World Texas IronMan 70.3 Waco held its inaugural event in the city on October 26.

Cameron Park is a 416-acre (168 ha) urban park featuring playgrounds, picnic areas, a cross-country running track, and a disc golf course. In 2009, the US Department of the Interior designated the Cameron Park Trail System as a National Recreation Trail. The park also contains Waco's 52-acre (21 ha) zoo, the Cameron Park Zoo.

Waco has a council-manager form of government. Citizens are represented on the City Council by six elected members; five from single-member districts and a mayor who is elected at-large. The city offers a full line of city services typical of an American city this size, including: police, fire, Waco Transit buses, electric utilities, water and wastewater, solid waste, and the Waco Convention and Visitors Bureau.

The first traffic circle in Texas was constructed in Waco in 1933 at the intersections of US 81 and US 77. It was later expanded to include intersections with Valley Mills Dr. and La Salle Ave. Drivers were confused and upset by the circle when it was first constructed, which even led to lawsuits. In 2013 a lone star was added to the center of the circle. Lane markings and new signage were added in 2018 to improve traffic flow and to help guide drivers.

The Waco area is home to three airports. Waco Regional Airport (ACT) serves the city with daily flights to Dallas/Fort Worth International via American Eagle.
