The Colorado Republican Party is the state affiliate of the Republican Party in the U.S. state of Colorado. The party's headquarters is located in Greenwood Village, Colorado.

The Republican Party was dominant in the state as recently as the mid-2000s, however it has declined over the subsequent decades. After the 2020 elections, Republicans held the smallest amount of political power in the state government since World War II. This decline has been attributed to various factors, including the party moving too far right for the state, changing demographics, mismanaged campaign money, internal party divisions, a better organized Democratic Party, and the unpopularity of Donald Trump in the state.

The party fared even poorer in the 2022 elections, in which Democrats swept every statewide office by a double-digit margin, expanded their majority in the state's U.S. House delegation, and further expanded their supermajorities in both chambers of the legislature. Since 2023, the party has faced further revenue loss and party infighting, with the party veering further towards the far-right after the election of Dave Williams as party chair, and an overall further decline of influence in the state.
