The 1986 United States House of Representatives elections was held on November 4, 1986, to elect U.S. Representatives to serve in the 100th United States Congress. They occurred in the middle of President Ronald Reagan's second term in office, while he was still relatively popular with the American public. As in most mid-term elections, the president's party — in this case, the Republican Party — lost seats, with the Democratic Party gaining a net of five seats and cementing its majority. These results were not as dramatic as those in the Senate, where the Republicans lost control of the chamber to the Democrats.
