The 2024 United States House of Representatives elections in Colorado were held on November 5, 2024, to elect the eight U.S. representatives from the State of Colorado, one from each of the state's congressional districts. The elections coincided with the 2024 U.S. presidential election, as well as other elections to the House of Representatives, elections to the United States Senate, and various state and local elections. The primary election took place on June 25, 2024.
As a result of the Republicans picking up the eighth district, the Democratic Party lost its majority in Colorado's U.S. House delegation that they earned in 2018.

## District 1

The 1st district includes almost all of Denver, as well as the enclaves of Glendale and Holly Hills. The incumbent was Democrat Diana DeGette, who was re-elected with 80.3% of the vote in 2022.

## District 3

The 3rd district encompasses the Colorado Western Slope, including the cities of Montrose, Pueblo, and Grand Junction. The incumbent was Republican Lauren Boebert, who was re-elected with 50.1% of the vote in 2022. Due to Boebert's narrow re-election in 2022, and her decreasing popularity, she dropped her bid in this district, and instead ran in the neighboring 4th district, which is more heavily Republican. Consequently, this seat became open.
