# 2008 United States House of Representatives elections

The 2008 United States House of Representatives elections were held on November 4, 2008, to elect members to the United States House of Representatives to serve in the 111th United States Congress from January 3, 2009, until January 3, 2011. It coincided with the election of Barack Obama as president. All 435 voting seats, as well as all 6 non-voting seats, were up for election. The Democratic Party, which won a majority of seats in the 2006 election, expanded its control in 2008.
The Republican Party, hoping to regain the majority it lost in the 2006 election or at least expand its congressional membership, lost additional seats. With one exception (Louisiana's 2nd district), the only seats to switch from Democratic to Republican had been Republican-held prior to the 2006 elections. Republicans gained five Democratic seats total, while losing 26 of their own, giving the Democrats a net gain of 21 seats, effectively erasing all gains made by the GOP since 1994. In addition, with the defeat of Republican congressman Chris Shays in Connecticut's 4th district, this became the first time since the 1850s that no Republican represented the New England region.
The 10.6% popular vote advantage by the Democrats was the largest by either party since 1982, 26 years earlier, and as of 2024 remains the most recent time that either party won by a double-digit margin in the overall popular vote for the House of Representatives. Turnout increased due to the concurrent presidential election. The presidential election, 2008 Senate elections, and 2008 gubernatorial elections, as well as many other state and local elections, occurred on the same date. This was the first and, as of 2024, the only election since 1980 in which the party of a newly elected president simultaneously gained seats in the House. It is also the most recent, and only time since 1988 that the incumbent president's party lost House seats in a presidential election year.
As of 2024, this remains the last election in which Democrats won House seats in Idaho, North Dakota, and South Dakota; and the last election in which Democrats won a majority of seats in Arkansas, Indiana, Mississippi, Ohio, Tennessee, West Virginia, and Wisconsin. It is also the last time Republicans won a seat in Delaware.
