The 2012 United States House of Representatives elections in Arizona were held on Tuesday, November 6, 2012, to elect the nine U.S. representatives from the state, one from each of the state's nine congressional districts, including the newly created 9th district following the 2010 United States census. The elections coincided with other federal and state elections, including a quadrennial presidential election, and a U.S. Senate election. Primary elections were held on August 28, 2012.

Arizona was one of five states (along with Wisconsin, Michigan, Pennsylvania, and North Carolina) where the party that won the most seats did not win the most votes in the state. Provided by Wikipedia
