Colorado's 3rd congressional district is a congressional district in the U.S. state of Colorado. It takes in most of the rural Western Slope in the state's western third portion, with a tendril in the south taking in some of the southern portions of the Eastern Plains. It includes the cities of Grand Junction, Durango, Aspen, Glenwood Springs, Ignacio, and Pueblo. The district is currently represented by Republican Lauren Boebert. The district was represented from 1987 to 1993 by Ben Nighthorse Campbell before he ran for the U.S. Senate and switched parties from Democratic to Republican. The district's former representative Scott R. Tipton lost renomination in 2020 to the more conservative Boebert in what was considered a major upset. Boebert went on to win the general election on November 3, 2020, and assumed office on January 3, 2021. The district is mainly rural and leans Republican, though not as much as the neighboring 4th district. However, the Democrats have a strong base in counties on the I-70 corridor and Pueblo, as well as liberal ski towns such as Aspen, thus keeping the seat somewhat competitive.
