Lyman County, County in central South Dakota, United States.
Lyman County extends over 1,707 square miles of land, with the Missouri River flowing along its northern and eastern boundaries and the White River marking its southern edge.
The Dakota Territorial Legislature formed Lyman County in January 1873, though it remained unorganized until May 1893 when W.P. Lyman received recognition as its namesake.
The county population includes substantial German, Irish, and Norwegian ancestries, with Native American communities representing more than one-third of current residents.
Interstate 90 and U.S. Highways 83 and 183 connect the communities within Lyman County, where Kennebec functions as the administrative center since 1922.
The county recorded its highest population of 10,848 residents during the 1910 census, which represents nearly triple the current number of inhabitants.
