The Congressional Progressive Caucus (CPC) is a congressional caucus affiliated with the Democratic Party in the United States Congress. The CPC represents the progressive faction of the Democratic Party. It was founded in 1991 and has grown since then, becoming the second-largest Democratic caucus in the House of Representatives.

As of July 19, 2024, the CPC has 98 members (95 voting representatives, one non-voting delegate, and one senator), making it the second-largest ideological caucus in the House Democratic Caucus by voting members, behind the New Democrat Coalition. The CPC is chaired by U.S. representative Greg Casar (D-TX). In addition, the CPC is affiliated with the Congressional Political Caucus PAC, a political action committee which is led by members of the caucus.

The CPC was established in 1991 by U.S. representatives Ron Dellums (D-CA), Lane Evans (D-IL), Thomas Andrews (D-ME), Peter DeFazio (D-OR), Maxine Waters (D-CA) and Bernie Sanders (I-VT). Additional representatives joined soon thereafter, including Major Owens (D-NY), Nydia Velázquez (D-NY), David Bonior (D-MI), Bob Filner (D-CA), Barney Frank (D-MA), Maurice Hinchey (D-NY), Jim McDermott (D-WA), Jerry Nadler (D-NY), Patsy Mink (D-HI), George Miller (D-CA), Pete Stark (D-CA), John Olver (D-MA), Nancy Pelosi (D-CA), and Lynn Woolsey (D-CA). Sanders was the first CPC chairman.

The founding CPC members were concerned about the economic hardship imposed by the deepening recession and the growing inequality brought about by the timidity of the Democratic Party response in the early 1990s. On January 3, 1995, at a standing room only news conference on Capitol Hill, they were the first group inside Congress to chart a comprehensive legislative alternative to U.S. speaker Newt Gingrich and the Republican Contract with America. The CPC's agenda was framed as "The Progressive Promise: Fairness".
