Winner in neighboring Tripp County serves as Todd County's administrative center.

Todd County is a county in the U.S. state of South Dakota. As of the 2020 United States Census, the population was 9,319. Todd County does not have its own county seat. Instead, Winner in neighboring Tripp County serves as its administrative center. Its largest city is Mission. The county was created in 1909, although it remains unorganized. The county was named for John Blair Smith Todd, a delegate from Dakota Territory to the United States House of Representatives and a Civil War general.

The county lies entirely within the Rosebud Indian Reservation and is coterminous with the main reservation (exclusive of off-reservation trust lands, which lie in four nearby counties). Its southern border is with the state of Nebraska. It is one of five South Dakota counties entirely within an Indian reservation. The county's per-capita income makes it the third poorest county in the United States. Unlike many rural counties in South Dakota, since 1960, its net population has increased.


Until 1981 Todd, Oglala Lakota (formerly Shannon) and Washabaugh County, South Dakota, were the last unorganized counties in the United States. Although then organized, Todd did not receive a home rule charter until 1983. As noted above, it contracts with Tripp County for its Auditor, Treasurer, and Registrar of Deeds.


According to the U.S. Census Bureau, the county has a total area of 1,391 square miles (3,600 km2), of which 1,389 square miles (3,600 km2) is land and 2.3 square miles (6.0 km2) (0.2%) is water.
