Brittany Louise Pettersen (born December 6, 1981)[1] is an American politician serving as the U.S. representative from Colorado's 7th congressional district since 2023.

Pettersen earned a Bachelor of Arts degree in political science from the Metropolitan State University of Denver.

[6][7] The recall petition stated that Pettersen should be recalled because she supports taxpayer-funded heroin-injection sites, and because she supported SB 19-042 (the National Popular Vote bill), SB 19-181 (Comprehensive Oil and Gas Reform), HB 19-1032 (Comprehensive Human Sexuality Education), and HB 19-1177 (the Red Flag bill that allows a judge to prohibit an individual from possessing a firearm).

After Perlmutter announced that he would retire from the United States House of Representatives after the 2022 legislative session, Pettersen declared her candidacy for Colorado's 7th congressional district.

[14] On July 12, 2024, Pettersen called for Joe Biden to withdraw from the 2024 United States presidential election.
