Colorado's 31st Senate district is one of 35 districts in the Colorado Senate. It has been represented by Democrat Chris Hansen since 2020, following the resignation of fellow Democrat Lois Court.[3] [4]
District 31 is based in the central and southeastern neighborhoods of Denver, including Capitol Hill; the district also includes the Arapahoe County exclaves of Glendale and Holly Hills.[5]
The district is located entirely within Colorado's 1st congressional district, and overlaps with the 2nd, 5th, 6th, 8th, and 9th districts of the Colorado House of Representatives.[6] At 23 square miles, it is the smallest Senate district in the state.[1]
Colorado state senators are elected to staggered four-year terms; under normal circumstances, the 31st district holds elections in presidential years.
