The 1936 United States House of Representatives elections were elections for the United States House of Representatives to elect members to serve in the 75th United States Congress. They were held for the most part on November 3, 1936, while Maine held theirs on September 14. They coincided with President Franklin D. Roosevelt's landslide re-election. Roosevelt's Democratic Party gained twelve net seats from the Republican Party, bringing them above a three-fourths majority. This was the largest majority since Reconstruction, as the last time a party won so decisively was in 1866. To date, this was the last time that any party held three-quarters of all House seats, as well as the last time that a party won more than 300 House seats.
