Chapo Trap House (also referred to as Chapo) is an American socialist political comedy podcast launched in March 2016. Chapo Trap House is aligned with the dirtbag left, a style of contentious left-wing political discourse that eschews civility in favor of casual, blunt, often vulgar expression. Since its inception the show has been primarily hosted by Will Menaker along with a rotating cast of cohosts, which currently includes Felix Biederman, Matt Christman, and Amber A'Lee Frost, along with a variety of guest co-hosts. It is produced by Chris Wade.

The show has a democratic-socialist perspective, and its co-hosts are affiliated with the Democratic Socialists of America (DSA). The hosts are typically extremely critical of both the Republican Party and the Democratic Party, particularly its centrist wing. Chapo supported Bernie Sanders in his first presidential campaign in the 2016 Democratic presidential primaries and his second campaign in the 2020 Democratic presidential primaries.

The series was originally founded by Menaker, Biederman, and Christman in March 2016, with Brendan James as producer. Frost and Virgil Texas joined in November of that year. James was replaced with current producer Wade in November 2017. In 2018, an imprint of Simon & Schuster published The Chapo Guide to Revolution, co-written by four of the original hosts along with James. The book debuted at number six on The New York Times Best Seller list. Texas left the show in May 2021. Frost took a hiatus for most of 2023 to publish her memoir and audiobook, Dirtbag: Essays, while Christman has been on hiatus since September 2023 due to complications from a stroke.
