The 2012 United States House of Representatives elections in Iowa were held on Tuesday, November 6, 2012 to elect the state's four U.S. Representatives. The elections coincided with the elections of other federal and state offices, including a quadrennial presidential election. Primary elections were held on June 5, 2012.
The new congressional map, drawn by the state's Legislative Services Agency and passed with bipartisan support in the state House of Representatives and Senate, was signed into law by Governor Terry Branstad on April 19, 2011. Reflecting population shifts recorded in the 2010 United States Census, the new map decreases Iowa's representation from five congressional districts to four. As of 2016, this is the last time in which Democrats won more than one congressional district in Iowa.
Bruce Braley, a Democrat the incumbent representative from the 1st district in northeastern Iowa since 2007, ran in the new 1st district. Fellow incumbent Dave Loebsack, who lived within the boundaries of the new 1st district in Linn County, but who had represented southeastern Iowa's 2nd district since 2007, moved to Johnson County and ran in the new 2nd district. The 1st district has become more favorable to Democrats with the inclusion of Linn County and its loss of Scott County. Braley won the Democratic nomination unopposed.
