List of special elections to the United States House of Representatives

Below is a list of special elections to the United States House of Representatives. Such elections are called by state governors to fill vacancies that occur when a member of the House of Representatives dies or resigns before the biennial general election. Winners of these elections serve the remainder of the term and are usually candidates in the next general election for their districts.

In the United States, these contests have been called "special elections" because they do not always occur on Election Day like regular congressional elections. Despite their name, however, special elections to the U.S. House happen quite often. Furthermore, one published study shows that special elections are explained by the same factors as regular congressional elections.[1]
