This is a list of notable performances of third-party and independent candidates in elections to the United States House of Representatives.
In some of the listed cases a faction or factions of a state's major party ran against each other, often making it difficult to ascertain which was the mainline candidate and which was the bolter; in such cases, those candidates which are not listed on a standard major party line are still listed, but are not considered traditional third-party victories as often these candidates sat in Congress as affiliated party members (barring cases like Joe Lieberman who, upon winning re-election in 2006 as a third-party candidate, sat as an Independent Democrat).
Listed below are House elections in which a third-party or independent candidate won at least 5.0% of the vote.
Winners are shown in bold and marked "elected" or "re-elected".
In other words, they must solely be a minor party candidate.
