The 1974 United States House of Representatives elections were elections for the United States House of Representatives on November 5, 1974, to elect members to serve in the 94th United States Congress. They occurred in the wake of the Watergate scandal, which had forced President Richard Nixon to resign in favor of Gerald Ford. This scandal, along with high inflation, allowed the Democrats to make large gains in the midterm elections, taking 48 seats from the Republicans, and increasing their majority above the two-thirds mark. Altogether, there were 93 freshmen representatives in the 94th Congress when it convened on January 3, 1975. Those elected to office that year later came to be known collectively as "Watergate Babies." The gain of 49 Democratic seats was the largest pickup by the party since 1958. Only four Democratic incumbents lost their seats.

The Watergate scandal was a significant political controversy in the United States during the presidency of Richard Nixon from 1972 to 1974, ultimately resulting in Nixon's resignation. It originated from attempts by the Nixon administration to conceal its involvement in the June 17, 1972, break-in at the Democratic National Committee headquarters located in the Watergate Office Building in Washington, D.C.
