The United States Senate elections of 1854 and 1855 were elections which saw the final decline of the Whig Party and the continuing majority of the Democrats. Those Whigs in the South who were opposed to secession ran on the "Opposition Party" ticket, and were elected to a minority. Along with the Whigs, the Senate roster also included Free Soilers, Know Nothings, and a new party: the Republicans. Only five of the twenty-one Senators up for election were re-elected. As this election was prior to ratification of the seventeenth amendment, Senators were chosen by state legislatures.
