The 2012 United States House of Representatives elections were held on Tuesday, November 6, 2012. Elections were held for all 435 seats representing the 50 U.S. states and also for the delegates from the District of Columbia and five major U.S. territories.

House Democrats won a narrow plurality of the nation-wide vote,^[5]^[6] but House Republicans were able to retain a solid majority due to their advantage in the congressional redistricting process following the 2010 United States Census, and because of population distribution and many Democratic votes concentrated into urban and minority districts. The last time the majority party in the House was unable to receive a plurality of the popular vote was in 1996, where the GOP kept the House for similar reasons.^[7]^[8]

The winners of this election cycle will serve in the 113th United States Congress. This was the first congressional election using congressional districts apportioned based on the 2010 United States Census.

As of November 20 2012, all but two races had been decided: A recount is pending in North Carolina's 7th congressional district and a runoff will be held in Louisiana's 3rd congressional district on Saturday, December 8.

Democrats

Republicans

Incumbents defeated

As a result of redistricting, many incumbents are forced to compete against each other in the same district, which will result in a higher than usual number of incumbents being defeated in primaries.

In primary elections

Thirteen representatives lost renomination: Eight were lost in redistricting battles pitting incumbents against each other, and five incumbents lost nomination to non-incumbent challengers.

Democrats

Seven Democrats lost renomination: five in redistricting and two to a non-incumbent challenger.

Pre-election analysis and selected results

The following are the predictions for House districts where at least one out of the Cook Political Report, the Rothenberg Political Report, Roll Call, and Sabato's Crystal Ball did not agree that the district was "safe Democrat" or "safe Republican". Ratings from the New York Times are also included. Incumbents not running for re-election have parentheses around their name; "(Open)" means that the seat was created in a state that gained one or more seats as the result of the 2010 census; where two incumbents are shown, that is also because of redistricting.)

Separate elections

Five special elections were held in 2012.

Two elections were held separate from the November elections, as follows:
