The 2024 United States presidential election in Missouri took place on Tuesday, November 5, 2024, as part of the 2024 United States elections in which all 50 states plus the District of Columbia participated. Missouri voters chose electors to represent them in the Electoral College via a popular vote. The state of Missouri has 10 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.
Prior to the election, all major news organizations considered Missouri a state Trump would win, or a red state. Formerly a bellwether state, Missouri has trended towards the Republican Party in recent years and since the late 2010s has been considered a GOP stronghold at both the federal and state levels.
As he did in the previous two presidential elections, Republican Donald Trump easily won Missouri in 2024, this time by an 18.4% margin. This was 0.1% less than the 2016 margin.

Analysis
Missouri is a Midwestern state with heavy Southern cultural influence, having been a Southern border state and contested between the Union and Confederacy during the Civil War. A bellwether state for the bulk of the 20th century well into the 2000s (backing the winner of all but one presidential election for a century, from 1904 to 2004, the exception being 1956 by just 0.22% and less than 4,000 votes), Missouri has voted Republican in every presidential election since 2000. It is widely understood to have lost its bellwether status when Democrat Barack Obama of neighboring Illinois failed to carry the state in either of his presidential victories, followed by Republican Donald Trump carrying it by more than 15% in all three of his election bids.
The state is largely located in the conservative Bible Belt, with the southern portion of the state being part of the Upland South, Missouri has drifted away from being a political bellwether towards the Republican Party in the 21st century and is now a strongly red state, with Republicans occupying every statewide office since 2023. Democratic strength in Missouri is nowadays largely limited to the Kansas City and St. Louis areas, as well as the college town of Columbia.
Democrat Kamala Harris won the same jurisdictions that Joe Biden did in 2020, as did Hillary Clinton in 2016 and Obama in 2012: Jackson County, home to Kansas City; Boone County, home to Columbia; the independent city of St. Louis; and St. Louis County, which contains many of St. Louis's closest suburbs.
Despite losing the state, Harris did marginally better than Hillary Clinton in 2016 by margin in the state. 2024 Missouri Amendment 3 also narrowly passed by 3.2%, legalizing abortion in Missouri.
