The United States Senate elections of 1810 and 1811 were elections that had the majority Democratic-Republican Party gain one seat in the United States Senate. The minority Federalists had gone into the elections with such a small share of Senate seats (7 out of 34, or 20.6%) that they had won all of the elections, they would still not have controlled a majority. As these elections were prior to ratification of the seventeenth amendment, Senators were chosen by State legislatures.
