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 census, the population was 9,319.[2] Todd County does not have its own county seat. Instead, Winner in neighboring Tripp County serves as its administrative center.[3] Its largest city is Mission. The county was created in 1909, although it remains unorganized.[1][4] The county was named for John Blair Smith Todd, a delegate from Dakota Territory to the United States House of Representatives[1] 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.[5] 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.
