Corson County is a county in the U.S. state of South Dakota. As of the 2010 census, the population was 4,050. Its county seat is McIntosh. The county was named for Dighton Corson, a native of Maine, who came to the Black Hills in 1876, and in 1877 began practicing law at Deadwood.
The county is encompassed within the Standing Rock Indian Reservation, which extends into North Dakota. The Lakota people reside primarily in the South Dakota part of the reservation; the Yanktonai and Dakota live in that part in North Dakota. The Grand River, a tributary of the Missouri River, runs through the reservation.

Like Ziebach County, and unlike the arch-Republican white West River counties, Corson is a competitive, fluctuating swing county. It voted Democratic in the three elections from 2004 to 2012 – doing so by over twenty percentage points for Barack Obama in 2008 – but as with most Native American counties there was a substantial swing against Hillary Clinton in 2016.
