1810 and 1811 United States Senate elections

The 1810 and 1811 United States Senate elections were elections that had the Democratic-Republican Party maintain their majority in the United States Senate. The minority Federalists had gone into the elections with such a small share of Senate seats (8 out of 34, or 23.5%) that, had they won all of the elections, they would still not have reached a majority.

As these elections were prior to ratification of the seventeenth amendment, Senators were chosen by state legislatures.
