United States House of Representatives elections in Iowa, 2010

The 2010 House elections in Iowa occurred on November 2, 2010 and elected the members of the State of Iowa's delegation to the United States House of Representatives. Representatives are elected for two-year terms; those elected served in the 112th Congress from January 3, 2011 until January 3, 2013. Iowa has five seats in the House, apportioned according to the 2000 United States Census.

These elections were held concurrently with the United States Senate elections of 2010 (including one in Iowa), the United States House elections in other states, and various state and local elections. All five of Iowa's incumbent representatives were re-elected. As of 2016, this is the last time in which Democrats won a majority of congressional districts in Iowa.

In this liberal-leaning district based in northeastern Iowa, incumbent Democratic Congressman Bruce Braley ran for a third term against Republican attorney Ben Lange, Libertarian Rob Petsche, and independent candidate Jason Faulkner. Though Braley was overwhelmingly re-elected to his second term two years prior, the anti-Democratic mood in the country contributed to the Congressman experiencing a tough fight for re-election. The race attracted the attention of both national party organizations, and thousands of dollars were reserved for airtime by the DCCC and the NRCC. Though Braley emerged victorious on election day, it was by a slim 4,000 vote and two percent margin, which was the thinnest margin of victory out of the entire Iowa congressional delegation.

In a rematch from 2008, incumbent Democratic Congressman Dave Loebsack faced Republican challenger Mariannette Miller-Meeks when he ran for a third term in this southeastern Iowa-based district, the most liberal of the congressional districts in the state. Polling indicated that the race would be close, and both parties’ congressional campaign committees spent on television advertisements, but ultimately, Congressman Loebsack defeated Miller-Meeks by a 10,000 vote, five percent margin.
