Colorado's 7th congressional district is a congressional district in the U.S. state of Colorado. Formerly located only in the northeast part of the state, the district now encompasses the western parts of the Denver metropolitan area, including Golden, Lakewood, Arvada and Broomfield, along with the central Colorado counties of El Paso County, Jefferson, Park, Teller, Lake, Chaffee, Fremont, and Custer.

The district has been represented by Democrat Brittany Pettersen since 2023.

The 7th congressional district was created following the 2000 U.S. census and associated realignment and reapportionment of Colorado congressional districts. It formerly consisted of portions of Adams, Arapahoe, and Jefferson counties, see above for the more recent list. The boundaries were drawn by a court after the state legislature failed to agree on a redistricting plan.^[5]

As originally drawn, the 7th was a "fair fight" district that was split roughly 50-50 between Democrats and Republicans. The seat's original congressman, Republican Bob Beauprez, gave up the seat in 2006 to run for governor, and was succeeded by Democrat Ed Perlmutter. Since then, a growing Democratic trend in the Denver suburbs allowed Perlmutter to strengthen his hold on the seat.

Redistricting after the 2010 census shifted the district to the more populated portions of Jefferson County, making it slightly more Democratic. The 2020 census has changed the district significantly, absorbing the rural areas in the central portion of the state. While the district takes in much more rural population than before, the bulk of population still lives in Jefferson and Broomfield counties, giving the district a mildly Democratic tilt.
