Lincoln County, South Dakota
Lincoln County is a county in the U.S. state of South Dakota. It forms part of the Sioux Falls metropolitan area and lies adjacent to the Minnesota border, intersecting transportation corridors linked to Interstate 29, U.S. Route 18, and U.S. Route 81. The county is named for Abraham Lincoln and has experienced rapid suburban growth connected to regional hubs such as Sioux Falls, Worthington, Minnesota, and Sioux City, Iowa.
The area that became the county was traversed by Lewis and Clark Expedition routes and earlier indigenous trails used by the Santee Sioux and Omaha people prior to 19th-century settlement. Euro-American settlement accelerated after the Homestead Act of 1862 and following surveys by the General Land Office; county organization dates to the territorial era concurrent with the Dakota Territory legislature. Rail expansion by companies like the Chicago, Milwaukee, St. Paul and Pacific Railroad and the Chicago and North Western Transportation Company connected local agricultural markets to Minneapolis–Saint Paul and Omaha, Nebraska, encouraging towns such as Harrisburg, South Dakota and Tea, South Dakota to grow. During the 20th century, the county's development paralleled national trends tied to the Great Depression, New Deal, and postwar suburbanization influenced by the Federal-Aid Highway Act of 1956; more recent decades saw population shifts related to employment centers in Sioux Falls and institutions like Augustana University.
Located in southeastern South Dakota, the county lies within the Coteau des Prairies region and features glacially derived soils associated with the Laurentide Ice Sheet.

The county's climate is continental under the Köppen climate classification with influences from North American prairie ecosystems and migratory corridors used by species cataloged by the Audubon Society. Landscape elements connect to interstate corridors—Interstate 29 and U.S. Route 81—and to rail lines operated historically by BNSF Railway and Canadian Pacific Railway subsidiaries, shaping land use patterns between urbanizing suburbs and remaining agricultural tracts producing commodities like corn and soy tied to markets in Chicago and Kansas City, Missouri.
