2024 United States presidential election in Idaho

The 2024 United States presidential election in Idaho 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. Idaho voters will choose electors to represent them in the Electoral College via a popular vote. The state of Idaho has 4 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.

Idaho is a sparsely-populated Mountain state with an overwhelmingly-White population and an evangelical plurality, and thus a conservative stronghold. Since statehood, the only non-Republicans to win Idaho's electoral votes have been Populist James B. Weaver and Democrats William Jennings Bryan, Woodrow Wilson, FDR, Harry Truman, and landslide victor Lyndon B. Johnson. Idaho is indeed one of the most staunchly Republican states in the US, as no presidential Democratic candidate after LBJ's narrow 1964 win has come within 13 percentage points of winning the state; and Republicans have occupied all statewide offices since 2003. Thus, Idaho is expected to be easily won by the Republicans in 2024.

Incumbent president Joe Biden has declared he is no longer running for a second term and thus suspended his candidacy before the 2024 Democratic National Convention officially nominates a candidate. He has endorsed Vice President Kamala Harris for his replacement.
