Sioux Falls (/ˌsuː ˈfɔːlz/ SOO FALZ) is the most populous city in the U.S. state of South Dakota and the 121st-most populous city in the United States. It is the county seat of Minnehaha County and also extends into northern Lincoln County to the south, which continues up to the Iowa state line. The population was 192,517 at the 2020 census, and in 2022, its estimated population was 202,078. According to city officials, the estimated population had grown to 213,891 as of early 2024. The Sioux Falls metro area accounts for more than 30% of the state's population. Chartered in 1856 on the banks of the Big Sioux River, the city is situated in the rolling hills at the junction of interstates 29 and 90.

The history of Sioux Falls revolves around the cascades of the Big Sioux River. The falls were created about 14,000 years ago during the last ice age. The lure of the falls has been a powerful influence. Ho-Chunk, Ioway, Otoe, Missouria, Omaha (and Ponca at the time), Quapaw, Kansa, Osage, Arikara, Sioux, and Cheyenne people inhabited and settled the region previous to Europeans and European descendants. Numerous burial mounds still exist on the high bluffs near the river and are spread throughout the general vicinity. Indigenous people maintained an agricultural society with fortified villages, and the later arrivals rebuilt on many of the same sites that were previously settled. Lakota populate urban and reservation communities in the contemporary state and many Lakota, Dakota, and numerous other Indigenous Americans reside in Sioux Falls today.

French voyagers/explorers visited the area in the early 18th century. The first documented visit by an American of European descent was by Philander Prescott, who camped overnight at the falls in December 1832. Captain James Allen led a military expedition out of Fort Des Moines in 1844. Jacob Ferris described the Falls in his 1856 book "The States and Territories of the Great West".

Two separate groups, the Dakota Land Company of St. Paul and the Western Town Company of Dubuque, Iowa organized in 1856 to claim the land around the falls, considered a promising townsite for its beauty and water power. Each laid out 320-acre (1.3 km) claims, but worked together for mutual protection. They built a temporary barricade of turf which they dubbed "Fort Sod", in response to native tribes attempting to defend their land from the settlers. Seventeen men then spent "the first winter" in Sioux Falls. The following year the population grew to near 40.

Although conflicts in Minnehaha County between Native Americans and white settlers were few, the Dakota War of 1862 engulfed nearby southwestern Minnesota. The town was evacuated in August of that year when two local settlers were killed as a result of the conflict. The settlers and soldiers stationed here traveled to Yankton in late August 1862. The abandoned townsite was pillaged and burned.

Fort Dakota, a military reservation established in present-day downtown, was established in May 1865. Many former settlers gradually returned and a new wave of settlers arrived in the following years. The population grew to 593 by 1873, and a building boom was underway in that year. The Village of Sioux Falls, consisting of 1,200 acres (4.9 km), was incorporated in 1876 and was granted a city charter by the Dakota Territorial legislature on March 3, 1883.

The arrival of the railroads ushered in the great Dakota Boom decade of the 1880s. The population of Sioux Falls mushroomed from 2,164 in 1880 to 10,167 at the close of the decade. The growth transformed the city. A severe plague of grasshoppers and a national depression halted the boom by the early 1890s. The city grew by only 89 people from 1890 to 1900.

In the 1890s Sioux Falls became a destination for women seeking divorce due to having some of the nation's most permissive divorce laws and being accessible by rail. It was known as the "Divorce Colony" and remained a popular venue for divorces until South Dakota changed its residency requirements in 1908.

But prosperity eventually returned with the opening of the John Morrell meat packing plant in 1909, the establishment of an airbase and a military radio and communications training school in 1942, and the completion of the interstate highways in the early 1960s. Much of the growth in the first part of the 20th century was fueled by agriculturally based industry, such as the Morrell plant and the nearby stockyards (one of the largest in the nation).

In 1955 the city decided to consolidate the neighboring incorporated city of South Sioux Falls. At the time South Sioux Falls had a population of nearly 1,600 inhabitants, according to the 1950 census. It was the third largest city in the county after Sioux Falls and Dell Rapids. By October 18, 1955, South Sioux Falls residents voted 704 in favor and 227 against to consolidate with Sioux Falls. On the same issue, Sioux Falls residents voted on November 15 by the vote 2,714 in favor and 450 against.

In 1981, to take advantage of recently relaxed state usury laws, Citibank relocated its primary credit card center from New York City to Sioux Falls. Some claim that this event was the primary impetus for the increased population and job growth rates that Sioux Falls has experienced over the past quarter-century. Others point out that Citibank's relocation was only part of a more general transformation of the city's economy from an industrially based one to an economy centered on health care, finance, and retail trade.

Sioux Falls has grown at a rapid pace since the late 1970s, with the city's population more than doubling from 81,182 in 1980 to 192,517 in 2020.

On the night of September 10, 2019, the south side of Sioux Falls was hit by three strong EF2 tornadoes, severely damaging at least 37 buildings, including the Plaza 41 Shopping Center. One tornado hit the Avera Heart Hospital, damaging portions of the roof and windows, and causing seven injuries, including a man who fractured his skull as he was thrown into an exterior wall of the hospital. Another tornado hit the busy commercial district near the Empire Mall, injuring one woman inside her home. Another touched down on the far south side in a suburban residential area, tearing the roofs off homes. The total damage was more than $5 million.

According to the United States Census Bureau, the city has an area of 73.47 square miles (190.29 km), of which 72.96 square miles (188.97 km) is land and 0.51 square miles (1.32 km) is water. The city is in extreme eastern South Dakota, about 15 miles (24 km) west of the Minnesota border.

The Sioux Falls Metropolitan Statistical Area consists of four South Dakota counties (Lincoln, McCook, Minnehaha, and Turner) and one Minnesota county (Rock). The estimated population of this MSA in 2022 was 289,592, an increase of 4.6% from the 2020 census. In addition to Sioux Falls, the metropolitan area includes Canton, Brandon, Dell Rapids, Tea, Harrisburg, Worthing, Beresford, Lennox, Hartford, Crooks, Baltic, Montrose, Salem, Renner, Rowena, Chancellor, Colton, Humboldt, Parker, Hurley, Garretson, Sherman, Corson, Viborg, Irene, Centerville, Luverne, Hills, and Beaver Creek.

Due to its inland location and relatively high latitude, Sioux Falls has a humid continental climate (Köppen Dfa, bordering on Dwa) characterized by hot, humid summers and cold, dry winters. It is in USDA Plant Hardiness Zone 5a. The monthly daily average temperature ranges from 17.9 °F (−7.8 °C) in January to 74.4 °F (23.6 °C) in July; there are 15 days of maximums at or above 90 °F (32 °C) and 25 days with minimums at or below 0 °F (−18 °C) annually. Snowfall occurs mostly in light to moderate amounts during the winter, totaling 45.3 inches (115 cm). Precipitation, at 27.85 inches (707 mm) annually, is concentrated in the warmer months. This results in frequent thunderstorms in summer from convection being built up with the unstable weather patterns. Extremes range from −42 °F (−41 °C) on February 9, 1899 to 110 °F (43 °C) as recently as June 21, 1988.

In the beginning of the 21st century, Sioux Falls experienced a renaissance of cultural interest. The Sioux Empire Arts Council continues to lead in the Sioux Falls area arts scene and gives out Mayor's Awards each year in several categories for excellence demonstrated by Sioux Falls residents. The Sioux Falls SculptureWalk was the first visual evidence of the renaissance and is an attraction for both visitors and resident artists, hosting over 55 sculptures including a replica of the Michelangelo's David. Work was essential to the renovation of the original Washington High School into the Washington Pavilion (housing two performing arts, a visual arts, and a science center).

The Northern Plains Indian Art Market (NPIAM) was established in 1988 by American Indian Services, Inc., of Sioux Falls as the Northern Plains Tribal Arts Show (NPTA). Northern Plains Tribal Arts dominated the Sioux Falls art scene from its inception in 1988. American Indian Services produced the juried art show and market from 1988 to 2003. Since 2004, Sinte Gleca University of Rosebud has been the producing organization. In the first 25 years of its existence—one of the longest-running Indian art shows in the country—over 800 artists from 7 northern plains states and two Canadian provinces exhibited at NPTA/NPIAM. Writers for national publications, filmmakers, and researchers have all joined the audiences over the years.

A permanent Northern Plains Tribal Arts collection is housed in the Egger Gallery at the Washington Pavilion. Since the Washington Pavilion opened its doors to the public in 1999, the collection has called the Visual Arts Center home. Originally the pieces were on an extended loan from American Indian Services, Inc.; in 2013, thanks to many supporters, the works were acquired under the title of the Augustana Tribal Arts Collection, and now officially belong to the Visual Arts Center.

As the 21st century began, poetry and literary events became more popular with the opening of the Sioux Empire Arts Council Horse Barn Gallery and due to a National Endowment for the Arts-supported Y Writer's Voice. The Y Writer's Voice included an annual reading series of 38 nationally known poets and writers, who performed works and youth workshops through the Sioux Falls Writers Voice in local performance spaces, at the YMCA after-school program, and in local schools, gaining national attention.

The Sioux Falls mayor's awards in literary arts designated movers and shakers during the growth and development of the literary arts scene. In addition to literary awards, there are mayor's awards in visual arts, performing arts, music, organizing in the arts, advocacy, and lifetime achievement, per the mayor's discretion.

The Sioux Falls Jazz and Blues Festival is a three-day outdoor musical event featuring two stages and is free to the public. It is held the third weekend in July at Yankton Trail Park. The Sioux Falls Jazz & Blues Society hosts national musicians during its annual concert series. Each year the series includes approximately five concerts with acts from all over the world. JazzFest, with over 125,000 in annual attendance, has expanded over the years to include the Jazziest Diversity Project, the All-City Jazz Ensemble, the Concert Series, and JazzFest Jazz Camp. 2016 was the festival's 25th anniversary year.

In 2019, Levitt at the Falls launched its first season of free concerts in a state-of-the-art outdoor amphitheater in Falls Park West.

The Visual Arts Center, also part of the Pavilion complex, hosts six galleries of changing exhibits, all free of charge. The Wells Fargo Cinedome is a multi-format 60 ft (18 m) dome theater that plays several films each month. The Cinedome also hosts the Sweetman Planetarium which has at least one show played everyday.

The Great Plains Zoo & Delbridge Museum provides the area with natural history and animal exhibits in its 50-acre (200,000 m) park. The taxidermy animals once hosted within the Delbridge Museum were removed in 2023 due to health concerns of the high amounts of arsenic in the mounts.

The USS South Dakota Battleship Memorial to the World War II battleship USS South Dakota is on State Highway 42 (West 12th Street) and Kiwanis Avenue.

The 114th Fighter Wing is at Joe Foss Field and houses F-16C/D fighter aircraft. The SD ANG unit is known for its support of community activities and services.

The city of Sioux Falls is led by a mayor–council (strong mayor) form of government. Mayoral elections occur every four years. City council seats are also contested every four years. Not all council members are elected in the same year, as the elections are staggered throughout even-numbered years. The council consists of five members elected to represent specific sections of the city and three additional seats that represent the city as a whole (that is, at-large). The council member position is designed to be part-time. Sioux Falls operates under a home rule charter as permitted by the South Dakota constitution.

In the 2004 presidential election, George W. Bush won both Minnehaha and Lincoln counties, receiving 56% and 65% of the vote, respectively. In 2008, Barack Obama won Minnehaha County by 0.7%, while John McCain won Lincoln County by 15%. Both counties have voted for the Republican nominee in every presidential election since 2012.

Sioux Falls is home to Augustana University, the University of Sioux Falls, Sioux Falls Seminary, Southeast Technical College, National American University, the South Dakota School for the Deaf, the University of South Dakota's Sanford School of Medicine (Sioux Falls campus), Stewart School and the South Dakota Public Universities and Research Center (formerly known as USDSU).

The Sioux Falls School District, which covers the majority of Sioux Falls, serves over 23,000 students living in Sioux Falls and some of its surrounding suburbs. There are 25 elementary schools, seven middle schools, and six high schools, including:

Other school districts in Minnehaha County which cover parts of Sioux Falls include: Tea Area School District 41-5, Brandon Valley School District 49-2, Tri-Valley School District 49-6, and Lennox School District 41-4. Within Lincoln County, other districts which cover parts of Sioux Falls include Tea Area and Harrisburg School District 41-2.

Bishop O'Gorman Catholic Schools is a centralized Catholic school system that includes eight schools: six elementary schools, all PreK-6 (St. Mary, St. Lambert, St. Michael-St. Katharine Drexel, Holy Spirit and Christ the King); one junior high (O'Gorman Junior High, grades 7–8); and one high school, O'Gorman (9–12). The junior and senior high O'Gorman schools are on the same campus. Approximately 2,800 students attend Bishop O'Gorman Catholic Schools. As of the 2009–10 school year the Sioux Falls Catholic School system's St. Joseph Cathedral School was closed.

The Lutheran Church-Missouri Synod operates two schools in Sioux Falls. Sioux Falls Lutheran School is on 37th street, while the Lutheran High School of Sioux Falls is on Western Avenue. In 2018, voters approved a plan to move Sioux Falls Lutheran School to a new building near the I-29/I-229 merge on south Boe Lane. Students moved to the new building at the beginning of the Spring 2020 semester.

The Wisconsin Evangelical Lutheran Synod has two schools in Sioux Falls: Bethel Lutheran and Good Shepherd Lutheran.

Other private schools include Sioux Falls Christian Schools, Christian Center, The Baan Dek Montessori, Cornerstone School, and the Open Arms Christian Child Development Center.

Most Sioux Falls residents travel and commute by car. Interstate 90 passes east to west across the northern edge of the city, while Interstate 29 bisects the western portion of the city from the north and south. Interstate 229 forms a partial loop around Sioux Falls, and connects with I-90 to the northeast and I-29 to the southwest. A grid design system for city streets is the standard for the central (older) area of the city; secondary streets in newer residential areas have largely abandoned this plan.

Due to current and expected regional growth, several large construction projects have been or will be undertaken. New interchanges have recently been added to I-29. An interchange was also completed on I-90 at Marion Road. I-29 has recently been improved from I-90 to 57th Street. This upgrade includes additional lanes and auxiliary lanes. Over the next decade, the city of Sioux Falls and the South Dakota Department of Transportation plan to construct a limited-access highway around the city's outer edges to the south and east, known as South Dakota Highway 100. This highway will start at the northern Tea exit (Exit 73 on I-29, 101st Street), run east on 101st Street, curve northeast east of Western Avenue, then turn north near Sycamore Avenue. It will end at the Timberline Avenue exit (Exit 402 on I-90). Sioux Falls' major roads include W 41st, Minnesota, Main, W 26th (which becomes Louise as it turns south), 12th, 49th, 57th, and Western.

Sioux Area Metro, the local public transit organization, operates 16 bus lines within the city, with most routes operating Monday through Saturday. Recently, the city added a new transfer station in Sioux Falls on Louise Avenue between 49th and 57th Streets. The Sioux Area Metro Paratransit serves members of the community who would otherwise not be able to travel by providing door-to-door service. Public transportation is supplemented with the SAM On Demand service that offers microtransit options.

Jefferson Lines runs long-distance bus routes to the Sioux Falls Bus Station. Non-transfer destinations include Grand Forks, Kansas City, Minneapolis, and Omaha. Until 1965 a branch of the Milwaukee Road train from Chicago, the Arrow, made a stop in Sioux Falls.

Many domestic airlines serve Sioux Falls Regional Airport.

The BNSF Railway provides freight rail service. Amtrak does not serve any community in South Dakota. On June 23, 2024, a BNSF railway bridge near near North Sioux City collapsed due to flooding.
