The 2024 United States presidential election in South Dakota took place on Tuesday, November 5, 2024, as part of the 2024 United States presidential election in which all 50 states plus the District of Columbia participated. South Dakota voters chose 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.
Republican Donald Trump carried the state by 29.7% in 2016 and again by 26.1% four years later. Trump won the state by 29.2% in 2024. Trump flipped back Ziebach County, which he won in 2016 but lost to Biden in 2020.

## Primary elections
### Democratic primary

The South Dakota Democratic was held on June 4, 2024, alongside primaries in the District of Columbia, Montana, New Jersey, and New Mexico.

### Republican primary

The South Dakota Republican primary was held on June 4, 2024, alongside primaries in Montana, New Jersey, and New Mexico. Under state law, no primary will be held if a candidate runs for a nomination unopposed. As Donald Trump was the only Republican candidate to file for the presidential primary, no popular vote was held.
