Des Moines (/dəˈmɔɪn/ ⓘ də-MOYN) is the capital and most populous city in the U.S. state of Iowa. It is the county seat of Polk County with parts extending into Warren County. It was incorporated on September 22, 1851, as Fort Des Moines, which was shortened to "Des Moines" in 1857. It is located on, and named after, the Des Moines River, which likely was adapted from the early French name, Rivière des Moines, meaning "River of the Monks". The city's population was 214,133 as of the 2020 census. The six-county metropolitan area is ranked 81st in terms of population in the United States, with 709,466 residents according to the 2020 census by the United States Census Bureau, and is the largest metropolitan area fully located within the state.

Des Moines is a major center of the United States insurance industry and has a sizable financial-services and publishing business base. The city is the headquarters for the Principal Financial Group, Ruan Transportation, TMC Transportation, EMC Insurance Companies, and Wellmark Blue Cross Blue Shield. Other major corporations such as Wells Fargo, Cognizant, Voya Financial, Nationwide Mutual Insurance Company, ACE Limited, Bayer, and Corteva have large operations in or near the metropolitan area. In recent years, Microsoft, Hewlett-Packard, and Facebook have built data-processing and logistical facilities in the Des Moines area.

Des Moines is an important city in U.S. presidential politics; as the state's capital, it is the site of the first caucuses of the presidential primary cycle. Many presidential candidates set up campaign headquarters in Des Moines. A 2007 article in The New York Times said, "If you have any desire to witness presidential candidates in the most close-up and intimate of settings, there is arguably no better place to go than Des Moines."

Des Moines takes its name from Fort Des Moines (1843–46), which was named for the Des Moines River. This was adopted from the name given by French colonists. Des Moines (.mw-parser-output .IPA-label-small{font-size:85%}.mw-parser-output .references .IPA-label-small,.mw-parser-output .infobox .IPA-label-small,.mw-parser-output .navbox .IPA-label-small{font-size:100%}pronounced [de mwan] ⓘ; formerly [de mwɛn]) translates literally to either "from the monks" or "of the monks".

One popular interpretation of "Des Moines" concludes that it refers to a group of French Trappist monks, who in the 17th century lived in huts built on top of what is now known as the ancient Monks Mound at Cahokia, the major center of Mississippian culture, which developed in what is present-day Illinois, east of the Mississippi River and the city of St. Louis. This was some 200 miles (320 km) from the Des Moines River.

Based on archaeological evidence, the junction of the Des Moines and Raccoon Rivers has attracted humans for at least 7,000 years. Several prehistoric occupation areas have been identified by archaeologists in downtown Des Moines. Discovered in December 2010, the "Palace" is an expansive 7,000-year-old site found during excavations prior to construction of the new wastewater treatment plant in southeast Des Moines. It contains well-preserved house deposits and numerous graves. More than 6,000 artifacts were found at this site. State of Iowa archaeologist John Doershuk was assisted by University of Iowa archaeologists at this dig.

At least three Late Prehistoric villages, dating from about AD 1300 to 1700, stood in or near what developed later as downtown Des Moines. In addition, 15 to 18 prehistoric Native American mounds were observed in the area by early settlers. All have been destroyed during development of the city.

Des Moines traces its origins to May 1843, when Captain James Allen supervised the construction of a fort on the site where the Des Moines and Raccoon Rivers merge. Allen wanted to use the name Fort Raccoon; however, the U.S. War Department preferred Fort Des Moines. The fort was built to control the Sauk and Meskwaki peoples, whom the government had moved to the area from their traditional lands in eastern Iowa. The fort was abandoned in 1846 after the Sauk and Meskwaki were removed from the state and shifted to the Indian Territory.

The Sauk and Meskwaki did not fare well in Des Moines. The illegal whiskey trade, combined with the destruction of traditional lifeways, led to severe problems for their society. One newspaper reported:

"It is a fact that the location of Fort Des Moines among the Sac and Fox Indians (under its present commander) for the last two years, had corrupted them more and lowered them deeper in the scale of vice and degradation, than all their intercourse with the whites for the ten years previous".

After official removal, the Meskwaki continued to return to Des Moines until around 1857.

Archaeological excavations have shown that many fort-related features survived under what is now Martin Luther King Jr. Parkway and First Street. Soldiers stationed at Fort Des Moines opened the first coal mines in the area, mining coal from the riverbank for the fort's blacksmith.

Settlers occupied the abandoned fort and nearby areas. On May 25, 1846, the state legislature designated Fort Des Moines as the seat of Polk County. Arozina Perkins, a school teacher who spent the winter of 1850–1851 in the town of Fort Des Moines, was not favorably impressed:

This is one of the strangest looking "cities" I ever saw... This town is at the juncture of the Des Moines and Raccoon Rivers. It is mostly a level prairie with a few swells or hills around it. We have a court house of "brick" and one church, a plain, framed building belonging to the Methodists. There are two taverns here, one of which has a most important little bell that rings together some fifty boarders. I cannot tell you how many dwellings there are, for I have not counted them; some are of logs, some of brick, some framed, and some are the remains of the old dragoon houses... The people support two papers and there are several dry goods shops. I have been into but four of them... Society is as varied as the buildings are. There are people from nearly every state, and Dutch, Swedes, etc.

In May 1851, much of the town was destroyed during the Flood of 1851. "The Des Moines and Raccoon Rivers rose to an unprecedented height, inundating the entire country east of the Des Moines River. Crops were utterly destroyed, houses and fences swept away." The city started to rebuild from scratch.

On September 22, 1851, Des Moines was incorporated as a city; the charter was approved by voters on October 18. In 1857, the name "Fort Des Moines" was shortened to "Des Moines", and it was designated as the second state capital, previously at Iowa City. Growth was slow during the Civil War period, but the city exploded in size and importance after a railroad link was completed in 1866.

In 1864, the Des Moines Coal Company was organized to begin the first systematic mining in the region. Its first mine, north of town on the river's west side, was exhausted by 1873. The Black Diamond mine, near the south end of the West Seventh Street Bridge, sank a 150-foot (46 m) mine shaft to reach a 5-foot-thick (1.5 m) coal bed. By 1876, this mine employed 150 men and shipped 20 carloads of coal per day. By 1885, numerous mine shafts were within the city limits, and mining began to spread into the surrounding countryside. By 1893, 23 mines were in the region. By 1908, Des Moines' coal resources were largely exhausted. In 1912, Des Moines still had eight locals of the United Mine Workers union, representing 1,410 miners. This was about 1.7% of the city's population in 1910.

By 1880, Des Moines had a population of 22,408, making it Iowa's largest city. It displaced the three Mississippi River ports: Burlington, Dubuque, and Davenport, that had alternated holding the position since the territorial period. Des Moines has remained Iowa's most populous city. In 1910, the Census Bureau reported Des Moines' population as 97.3% white and 2.7% black, reflecting its early settlement pattern primarily by ethnic Europeans.

At the turn of the 20th century, encouraged by the Civic Committee of the Des Moines Women's Club, Des Moines undertook a "City Beautiful" project in which large Beaux Arts public buildings and fountains were constructed along the Des Moines River. The former Des Moines Public Library building (now the home of the World Food Prize); the United States central Post Office, built by the federal government (now the Polk County Administrative Building, with a newer addition); and the City Hall are surviving examples of the 1900–1910 buildings. They form the Civic Center Historic District.

The ornate riverfront balustrades that line the Des Moines and Raccoon Rivers were built by the federal Civilian Conservation Corps in the mid-1930s, during the Great Depression under Democratic President Franklin D. Roosevelt, as a project to provide local employment and improve infrastructure. The ornamental fountains that stood along the riverbank were buried in the 1950s when the city began a postindustrial decline that lasted until the late 1980s. The city has since rebounded, transforming from a blue-collar industrial city to a white-collar professional city.

In 1907, the city adopted a city commission government known as the Des Moines Plan, comprising an elected mayor and four commissioners, all elected at-large, who were responsible for public works, public property, public safety, and finance. Considered progressive at the time, it diluted the votes of ethnic and national minorities, who generally could not command a majority to elect a candidate of their choice.

That form of government was scrapped in 1950 in favor of a council-manager government, with the council members elected at-large. In 1967, the city changed its government to elect four of the seven city council members from single-member districts or wards, rather than at-large. This enabled a broader representation of voters. As with many major urban areas, the city core began losing population to the suburbs in the 1960s (the peak population of 208,982 was recorded in 1960), as highway construction led to new residential construction outside the city. The population was 198,682 in 2000 and grew slightly to 200,538 in 2009. The growth of the outlying suburbs has continued, and the overall metropolitan-area population is over 700,000 today.

During the Great Flood of 1993, heavy rains throughout June and early July caused the Des Moines and Raccoon Rivers to rise above flood stage levels. The Des Moines Water Works was submerged by floodwaters during the early morning hours of July 11, 1993, leaving an estimated 250,000 people without running water for 12 days and without drinking water for 20 days. Des Moines suffered major flooding again in June 2008 with a major levee breach. The Des Moines River is controlled upstream by Saylorville Reservoir. In both 1993 and 2008, the flooding river overtopped the reservoir spillway.

Today, Des Moines is a member of ICLEI Local Governments for Sustainability USA. Through ICLEI, Des Moines has implemented "The Tomorrow Plan", a regional plan focused on developing central Iowa in a sustainable fashion, centrally-planned growth, and resource consumption to manage the local population.

According to the United States Census Bureau, the city has an area of 90.65 square miles (234.78 km2), of which 88.93 square miles (230.33 km2) is land and 1.73 square miles (4.48 km2) is covered by water. It is 850 feet (260 m) above sea level at the confluence of the Raccoon and Des Moines Rivers.

In November 2005, Des Moines voters approved a measure that allowed the city to annex parcels of land in the northeast, southeast, and southern corners of Des Moines without agreement by local residents, particularly areas bordering the Iowa Highway 5/U.S. 65 bypass. The annexations became official on June 26, 2009, as 5,174 acres (20.94 km2) and around 868 new residents were added to the city of Des Moines. An additional 759 acres (3.07 km2) were voluntarily annexed to the city over that same period.

The skyline of Des Moines changed in the 1970s and the 1980s, when several new skyscrapers were built. Additional skyscrapers were built in the 1990s, including Iowa's tallest. Before then, the 19-story Equitable Building, from 1924, was the tallest building in the city and the tallest building in Iowa. The 25-story Financial Center was completed in 1973 and the 36-story Ruan Center was completed in 1974. They were later joined by the 33-story Des Moines Marriott Hotel (1981), the 25-story HUB Tower and 25-story Plaza Building (1985). Iowa's tallest building, Principal Financial Group's 45-story tower at 801 Grand was built in 1991, and the 19-story EMC Insurance Building was erected in 1997.

During this time period, the Civic Center of Greater Des Moines (1979) was developed; it hosts Broadway shows and special events. Also constructed were the Greater Des Moines Botanical Garden (1979), a large city botanical garden/greenhouse on the east side of the river; the Polk County Convention Complex (1985), and the State of Iowa Historical Museum (1987). The Des Moines skywalk also began to take shape during the 1980s. The skywalk system is 4 miles (6.4 km) long and connects many downtown buildings.

In the early 21st century, the city has had more major construction in the downtown area. The new Science Center of Iowa and Blank IMAX Dome Theater and the Iowa Events Center opened in 2005. The new central branch of the Des Moines Public Library, designed by renowned architect David Chipperfield of London, opened on April 8, 2006.

The World Food Prize Foundation, which is based in Des Moines, completed adaptation and restoration of the former Des Moines Public Library building in October 2011. The former library now serves as the home and headquarters of the Norman Borlaug/World Food Prize Hall of Laureates.

At the center of North America and far removed from large bodies of water, the Des Moines area has a hot summer type humid continental climate (Köppen Dfa), with warm to hot, humid summers and cold, dry winters. Summer temperatures can often climb into the 90 Â°F (32 Â°C) range, occasionally reaching 100 Â°F (38 Â°C). Humidity can be high in spring and summer, with frequent afternoon thunderstorms. Fall brings pleasant temperatures and colorful fall foliage. Winters vary from moderately cold to bitterly cold, with low temperatures venturing below 0 Â°F (−18 Â°C) quite often. Snowfall averages 36.5 inches (93 cm) per season, and annual precipitation averages 36.55 inches (928 mm), with a peak in the warmer months. Winters are slightly colder than Chicago, but still warmer than Minneapolis, with summer temperatures being very similar between the Upper Midwest metropolitan areas.

The city has the largest African American population in Iowa.
