1828 and 1829 United States Senate elections

In the 1828 and 1829 United States Senate elections, the Jacksonian coalition, despite its leader's victory in the presidential election, lost a seat in the Senate to the opposing Anti-Jacksonian coalition.

Senators who called themselves "Anti-Jacksonian" or "National Republicans" were also called "Adams" or "Adams Men."

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