The 2012 United States House of Representatives elections in New Mexico were held on Tuesday, November 6, 2012, and elected the three U.S. representatives from the state, one from each of the state's three congressional districts. The elections coincided with those for other federal and state offices, including a quadrennial presidential election, and a U.S. Senate election.
The redrawn 1st district serves the central area of New Mexico, including almost three-fourths of Albuquerque. Incumbent Democrat Martin Heinrich, first elected in 2008, did not seek reelection, but instead ran for the U.S. Senate seat vacated by Jeff Bingaman.
Incumbent Republican Steve Pearce was elected in 2010, having previously served from 2003 until 2009. Pearce sought reelection in 2012.
Incumbent Democrat Ben Ray Luján was first elected in 2008. In April 2011 Luján declined to enter the U.S. Senate race and instead chose to seek reelection to the House of Representatives.
