Oglala Lakota County is one of two counties in South Dakota that does not have its own county seat (Todd County is the other). Hot Springs in neighboring Fall River County serves as its administrative center. It is also one of five South Dakota counties that are entirely on an Indian reservation. (The others are Corson, Dewey, Todd, and Ziebach.) [Article: Why Does a Reservation County also have a County Government?]
Oglala Lakota County was renamed in May of 2015, originally it had been named Shannon County. Until 1982 Oglala Lakota and Washabaugh County, South Dakota, were the last unorganized counties in the United States. Although it was organized and received a home rule charter that year, Oglala Lakota County, as noted above, contracts with Fall River County for its Auditor, Treasurer, Director of Equalization, State’s Attorney and Registrar of Deeds.
