2024 United States presidential election in South Dakota

The 2024 United States presidential election in South Dakota is scheduled to take place on Tuesday, November 5, 2024, as part of the 2024 United States elections in which all 50 states plus the District of Columbia will participate. South Dakota voters will choose electors to represent them in the Electoral College via a popular vote. The state of South Dakota has three electoral votes in the Electoral College, following reapportionment due to the 2020 United States census in which the state neither gained nor lost a seat.

South Dakota is sparsely populated state in the Great Plains, and is a Republican stronghold at both the state and presidential levels. It hasn't voted for a Democratic presidential candidate since Lyndon B. Johnson carried it in 1964, against the backdrop of his nationwide landslide victory; not even in 1972, when favorite son George McGovern lost his state by a wide margin of 8.6%. South Dakota is widely expected to back Donald Trump again in 2024.

Incumbent Democratic president Joe Biden is running for reelection to a second term.
