Third-party members of the United States House of Representatives

Third-party members of the United States House of Representatives are generally rare. Although the Republican party and Democratic party have dominated American politics in a two-party system since 1856, other political parties and independents have run, been elected and exerted influence.

This article lists all representatives since the end of Reconstruction or after the 45th United States Congress (1879) who were third-party affiliated or independent while they were in office, although dating them from the first year they were in the House in any affiliation.

Since 1877, there have been 111 third party U.S. Congress Representatives: 6 from the Modern era, 36 from the Progressive era, 44 from the Populist era, and 25 from the Greenback era.
