The 1906 United States House of Representatives elections were held for the most part on November 6, 1906, with Oregon, Maine, and Vermont holding theirs early in either June or September. They occurred in the middle of President Theodore Roosevelt's second term. Elections were held for 386 seats of the United States House of Representatives, representing 45 states, to serve in the 60th United States Congress (Oklahoma would later gain statehood in 1907 and increase the House membership to 391).
As in many midterm elections, the President's Republican Party lost seats to the opposition Democratic Party, but retained a large overall majority. Dissatisfaction with working conditions and resentment toward union busting among industrial laborers in the Mid-Atlantic and Midwest caused these groups to turn out to the polls in large numbers in support of the Democratic Party. However, gains in these regions were not enough to remove the Republican majority or the firm support that the party held among the middle class.
In 1906, three states, with 8 seats among them, held elections early:
Oklahoma was admitted in 1907 and held its first congressional elections on September 17, 1907.
