1934 United States House of Representatives elections

The 1934 United States House of Representatives elections were elections for the United States House of Representatives to elect members to serve in the 74th United States Congress. They were held for the most part on November 6, 1934, while Maine held theirs on September 10. They occurred in the middle of President Franklin D. Roosevelt's first term. The Democratic Party continued its progress, gaining another 9 net seats from the opposition Republican Party, who also lost seats to the Progressive Party. The Republicans were reduced below one-fourth of the chamber for the first time since the creation of the party. The Wisconsin Progressive Party, a liberal group which allied with the Democrats, also became a force in Wisconsin politics.

The 1934 elections can be seen as a referendum on New Deal policies. While conservatives and people among the middle class who did not bear the brunt of the depression saw New Deal programs as radical, lower-income voters overwhelmingly voted in this election cycle to continue the implementation of Roosevelt's agenda. This marked the first time that an incumbent president's party did not lose seats in either house in a midterm election, followed by 1998 and 2002.
