President before election Jimmy Carter Democratic Elected President Ronald Reagan Republican

The 1980 United States presidential election in Colorado took place on November 4, 1980. All 50 states and The District of Columbia, were part of the 1980 United States presidential election. State voters chose seven electors to the Electoral College, who voted for president and vice president.

Colorado was won by the Republican Party candidate, former California Governor Ronald Reagan by a landslide of 24 points, defeating Democratic incumbent president Jimmy Carter. John B. Anderson, an Illinois Republican congressman running on the National Unity ticket, received 11% of the vote.

As of the 2024 presidential election, this is the last occasion where a Republican candidate carried the City and County of Denver. Since then, Denver has remained a reliable Democratic stronghold in presidential elections, which would eventually cause the state to flip consistently Democratic from 2008 onward.
