During the 110th United States Congress, there were two special elections for seats in the Senate, both in 2008, and 13 for seats in the House, five in 2007 and eight in 2008. Democrats gained three House seats at the expense of Republicans in 2008, but the incumbent party won all the other special elections.

Roger Wicker, formerly the representative of Mississippi's 1st congressional district, was appointed by Governor Haley Barbour on December 31, 2007, to fill the vacancy caused by the December 18 resignation of Trent Lott. It had been speculated that Lott wished to resign before a new lobbying reform law, effective the first day of 2008, took effect; having resigned before the end of 2007, Lott may become a lobbyist in 2009 instead of 2010. Controversy arose when Barbour called for the special election to be held on the same day as the general election. As a result, Mississippi's Attorney General Jim Hood challenged Barbour in court, claiming that the special election needed to be held within 100 days of Lott's resignation, as per state law. Initially, a Mississippi Circuit Court judge sided with Hood, ruling that the election take place on or before March 19, 2008. However, Barbour filed an appeal to the Mississippi Supreme Court, which overturned the earlier ruling and set the special election for November 4, 2008.
Democratic former Governor Ronnie Musgrove challenged Wicker. Another Democrat, former Congressman Ronnie Shows, also filed to run, but he withdrew in February 2008 and endorsed Musgrove. Wicker beat Musgrove 55% to 45%.
John Barrasso was appointed by Governor Dave Freudenthal (D) on June 22, 2007 to fill the senate seat of Republican Craig L. Thomas, who died on June 4. Wyoming law requires that the interim senator be affiliated with the same political party as the departed senator. Barrasso ran in the November 4, 2008 special election, held on the day of the 2008 presidential election, to serve out the remainder of Thomas' term, which expires in January 2013.
On the Democratic side, Casper City Councilman Keith Goodenough announced his candidacy. In the primary on August 19, Goodenough was defeated by a political newcomer, Gillette defense attorney Nick Carter, who became Barrasso's opponent in the general election.
Barrasso won on election day, taking 73% of the vote and winning every county in the state.
The thirteen special elections to the 110th United States Congress are listed below by election date.
