The 1976 United States presidential election in South Dakota was held on November 2, 1976. Incumbent President Gerald Ford won the state of South Dakota, defeating Democratic candidate Jimmy Carter by a slim margin of 1.48 percentage points. Ford won all of South Dakota's four electoral votes, but lost the general election to Carter.
South Dakota weighed in as 4% more Republican than the national average. As of the 2016 presidential election, this is the last election in which Codington County, Edmunds County, Faulk County, Gregory County, and McCook County voted for the Democratic candidate. This is also the last time a Democrat won any of South Dakota's congressional districts, namely the 1st, as both it and the 2nd would be eliminated after the 1980 census.
