Boynton Beach is a city in Palm Beach County, Florida, United States. It is situated about 57 miles (92 km) north of Miami. The 2020 census recorded a population of 80,380. Boynton Beach is located in the Miami metropolitan area, which was home to 6,138,333 people at the 2020 census. The city is named after Nathan Boynton, a Civil War major and Michigan politician who became one of the first settlers in the area in 1895. Boynton Beach is located north of Delray Beach, south of Hypoluxo and Lantana, and east of Golf, while the municipalities of Briny Breezes, Gulf Stream, Manalapan, and Ocean Ridge are situated to the east across the Intracoastal Waterway.

Native Americans inhabited modern-day Boynton Beach thousands of years ago, with a burial mound west of the city including artifacts dating as far back as roughly 150 BCE. The first non-indigenous settlers, Dexter Hubel and his family, arrived in 1877. Major Boynton moved to present-day Boynton Beach in 1895, building the Boynton Hotel and bringing contingents from Michigan, many of whom practiced farming or established businesses in the vicinity of Ocean Avenue. Byrd and Fred Dewey filed the original plat for the Town of Boynton in 1898, although official incorporation did not occur until 1920. The oceanfront section of Boynton Beach split off in 1931 and became Ocean Ridge in 1939. Boynton Beach's population grew rapidly in the first few decades following World War II, with more than a three-fold increase in the 1950s, while development of the city expanded westward, particularly in the 1980s.

Today, Boynton Beach is the third-most populous municipality in Palm Beach County, behind only West Palm Beach and Boca Raton. The area along Congress Avenue south of Gateway Boulevard includes a large concentration of restaurants and retail stores at the Boynton Beach Mall, the Boynton Town Center, and Renaissance Commons. Boynton Beach also has several arts and culture facilities, such as the Boynton Woman's Club and Schoolhouse Children's Museum & Learning Center.

Archaeological evidence indicates Native American inhabitation of the region dating back thousands of years, with Ais, Calusas, Jaegas, Mayaimis, and Tequesta settling in or near modern-day Palm Beach County. A complex of mounds west of present-day Boynton Beach and near the Loxahatchee National Wildlife Refuge includes shards of pottery possibly from 150 BCE. An excavation of the site also yielded beads and glass from as recently as the 16th century, which are believed to have been influenced by the Spanish.: 10–11 

Captain James A. Armour, head keeper of the Jupiter Inlet Lighthouse, filed the first land claim in modern-day Boynton Beach in 1875, although it is unlikely he lived there.: 11  Two years later, Dexter Hubel of Michigan and his family settled in the area, but they had to live at the Orange Grove House of Refuge in present-day Delray Beach until their house was built.: 12 

In 1894, two years before Henry Flagler built his railroad, a former American Civil War major named Nathan Boynton first set eyes on the area that now bears his name.: 14  Boynton hailed from Port Huron, Michigan.: 13  He was so impressed by the natural beauty of the year-round sunshine and pristine beaches, he built the famous Boynton Hotel, where he also spent winters with his family. The hotel, which opened in 1897, included accommodations for 100 guests and 5 guest cottages.: 15  Major Boynton died on May 27, 1911, in Port Huron, but the hotel lasted until 1925.: 32  Several commercial and residential buildings also sprang up along Ocean Avenue in the late 1890s, including the first post office in 1896.

The first settlers, whom Boynton had brought along from Michigan, soon realized that many fruits and vegetables thrived in the fertile climate. Pineapples, tomatoes, mangoes, and citrus fruit were packed in crates and shipped across the country on the newly built Florida East Coast Railroad. Alonzo King and Samuel Cade, both African American farmers, taught these early settlers methods for cultivating muck soil and dealing with the presence of mosquitos and rattlesnakes.

Boynton Beach was founded on September 26, 1898, when Byrd Spilman Dewey and her husband Fred S. Dewey filed the original plat in the Dade County courthouse for the Town of Boynton. Fred S. Dewey, one of Flager's secretaries, bought a large area of land west of the Intracoastal Waterway earlier that year. He subdivided the land into 2.5 acre (1.0 ha) tracts for agricultural uses, which he sold to settlers and hotel workers. Buyers of these tracts also received a plot within the residential sections of the townsite.: 17 

A wood frame schoolhouse opened in 1900 at Ocean Avenue and Seacrest Boulevard, replacing a smaller, temporary building.: 20  By then, the town had a population of 83. Just four years later, a second, two-room school building opened as the community continued to grow quickly.: 20  Overcrowding at the school at Ocean Avenue and Seacrest Boulevard also led to the construction of another school in 1913, a two-story concrete building with six classrooms.: 25  This building is listed on the National Register of Historic Places and was converted into the Schoolhouse Children's Museum & Learning Center in 2001.

The first bridge crossing the Intracoastal Waterway opened in 1911 at Ocean Avenue. During the same year, the Boynton Woman's Club and the Florida Federal of Women's Clubs established the first library in Boynton, then staffed by volunteers. The 1910s also saw the creation of the town's first bank in 1915 and first ocean road (State Road A1A) in 1916.: 7 

The town of Boynton was officially incorporated in 1920 upon the approval of 48 out of the 50 qualified voters who met at the Boynton Lumber Club on April 14. G. E. Coon became the first mayor, Fred Benson became the first town marshall, and A. A. Atwater, J. P. Bowen, C. M. Jensen, A. C. Shepherd, and W. S. Shepherd became the first aldermen.: 26  Shortly before the incorporation of Boynton, the 1920 census recorded a population of 671 people in Palm Beach County's fourth precinct, which also included Hypoluxo and the area that now comprises Ocean Ridge. The name "Boynton Beach" was first used by a community that broke off from the Town of Boynton in 1931. In 1939, that community changed its name to "Ocean Ridge" while The Town of Boynton took the name "Boynton Beach" in 1941.

Utility services also began in Boynton in the early 1920s. John Meredith brought electricity to the town in 1921, the same year as the installation of a sewage system. Additionally, in 1923, a municipal water system began operating.: 7  Telephone service arrived in Boynton near the end of the 1920s.: 8 

Boynton Beach Oceanfront Park is located just north of the original Boynton Hotel site. In 1921, the Town of Boynton acquired the beach site from Lewis S. Howe by eminent domain for park and recreation purposes. The beach casino was built in 1928 and featured a large dining hall, locker rooms and showers and residents used the casino for parties and social gatherings. The casino was demolished in 1967 and the property remained part of the beach park. From the 1920s to today, Boynton Beach Oceanfront Park has been popular with residents and visitors alike. In the mid-1990s, the park underwent a major renovation during which the boardwalk was rebuilt out of recycled plastic. Boynton Beach's Oceanfront Park was voted the best family beach in Palm Beach County by The Palm Beach Post in 2001. In 2011 the boardwalk was renovated again, replacing the plastic with ipe (pronounced ee-pay) wood (commonly known as Brazilian walnut). In 2012 improvements were made to the buildings along the boardwalk, including total refurbishment of the restrooms.

In 1926, the Seaboard Air Line Railway entered what was then simply Boynton, spurring land development a mile inland near the Seaboard station, including the town's first planned subdivision, Lake Boynton Estates. As land became more valuable, areas along the Intracoastal Waterway and the Federal Highway in Boynton also saw housing developments. To the west, many dairies were founded so that the Boynton area became the main milk supplier for Palm Beach County. By the 1970s, the dairies were no longer profitable and these lands too were converted to housing developments.

Three hurricanes affected Boynton between 1926 and 1928.: 7–8  The 1928 Okeechobee hurricane in particular caused significant impacts, destroying 46 homes and 18 buildings, including a church, a hotel, and the town hall.: 8  Additionally, the storm damaged 255 homes and 34 buildings, including the high school, where 15 people suffered injuries after auditorium roof collapsed. The hurricane rendered 56 families homeless and caused approximately $1 million in damage.: 8  The Boynton town government faced financial struggles in the aftermath of the 1928 hurricane and during the Great Depression, but received some assistance from the Florida Legislature and negotiated with bondholders for additional debt relief. Funds from the state also resulted in the resurfacing of Dixie Highway,: 38  while federal funds were used to construct a new bridge across the Intracoastal Waterwater in 1935.: 39 

Boynton Beach grew very rapidly in the 1950s, with its population expanding from 2,542 people in 1950 to 10,467 people in 1960, a 311.8% increase. Significant construction projects during the decade included a new city hall at Boynton Beach Boulevard and Seacrest Boulevard in 1958 and Bethesda Memorial Hospital in 1959. The expansion of beachfront recreation facilities also occurred as the city purchased more coastal properties.

During the 1960s, the city constructed a civic center in 1960, a public library in 1961, and a new water treatment plant in 1962. A second bridge across the Intracoastal Waterway opened in 1967 along 15th Avenue (Woolbright Road).: 8  The decade also marked beginning of the construction of Interstate 95 through the city (completed in 1977),: 42–43  the westward expansion of Boynton Beach Boulevard in 1962, the southward extension of Congress Avenue in 1966. Additionally, residential projects such as the large Hampshire Gardens, Leisureville, and Sterling Village sprang up, causing further growth and economic development.: 42–43  A few civil rights movement protests also occurred in Boynton Beach during the 1960s, including a sit-in at the Royal Castle Restaurant and the arrival of approximately 30 African Americans at a whites-only section of the beach in 1962.

Several developments also brought a substantial economic boost to Boynton Beach in the 1980s. First, Motorola opened a new paging plant in the city in 1983,: 43  although the complex closed in 2004, about 10 years after its peak, when the facility employed approximately 3,500 people. Next, the Boynton Beach Mall and Quantum Corporate Park opened in 1985 and 1988, respectively. Additionally, Tri-Rail began operating in 1989, opening its station in Boynton Beach in December of that year. Each of these factors attracted more businesses to the area and generated rapid population increases in the city's western suburbs.: 43 

Hurricane Wilma struck Boynton Beach on October 24, 2005, causing widespread damage to homes and businesses. In 2006, the city government authorized the demolition of the historic Seaboard rail station, which had survived intact in private hands since passenger service to the station halted in 1971.

On March 8, 2022, Ty Penserga was elected mayor of Boynton Beach in Florida, making him the first openly gay mayor of the city as well as the first out LGBTQ Asian American mayor elected in Florida state history. A high school biology and chemistry teacher, Penserga was sworn into office by State Attorney Dave Aronberg.

The year 2006 saw an increase in gang-related violent crime. This mirrored a similar increase across Palm Beach County. A gang-related shooting that resulted in a death at the city's popular Boynton Beach Mall on Christmas Eve of 2006 caught the national attention on many news networks, such as CBS. There were ten known operating gangs in the city as of 2007, according to police, including the notorious South Florida Haitian Zoe Pound gang. As of 2009, countywide gang violence had fallen three percent.

On January 27, 2012, Mayor Jose Rodriguez was suspended from office by the state governor for trying to influence a police investigation into his personal affairs.

The crime rate started decreasing in 2017 and attained its lowest number in 20 years in 2020. According to the Florida Department of Law Enforcement's 2020 Annual Crime Report, the total crime rate decreased by 28 percent in the city compared to 2019 and 64 percent compared to 2001. Violent crime, which includes murder, rape, robbery and aggravated assault, decreased 8.5 percent. Property crime, which includes burglary, larceny and motor vehicle theft, dropped by 32.2 percent. Florida's total crime volume dropped 14.1 percent compared to 2019.

Boynton Beach Police Chief Michael G. Gregory attributed the decrease to focused efforts, an all-hands-on-deck approach and "using a multitude of tactics and crime fighting strategies that are constantly evolving based on crime patterns".
