The 2012 United States House of Representatives elections in Missouri were held on Tuesday, November 6, 2012, and elected the eight U.S. representatives from the state of Missouri, a loss of one seat following the 2010 United States census. The elections coincided with the elections of other federal and state offices, including a federal quadrennial presidential election, concurrent statewide gubernatorial election, quadrennial statewide lieutenant gubernatorial election, and an election to the U.S. Senate.

Redistricting A new congressional map was passed by the Missouri General Assembly on April 27, 2011. The map was vetoed by Democratic Governor Jay Nixon on April 30, but Nixon's veto was overridden by the General Assembly on May 4, making the plan law. The map effectively eradicated the former 3rd district, which had been represented by Democrat Russ Carnahan since 2005, splitting it between the districts represented by Republicans Blaine Luetkemeyer and Todd Akin and Democrat William Lacy Clay, Jr. The bulk of the old 9th district became the new 3rd district.

Declined Russ Carnahan, incumbent U.S. representative for the 3rd district

Campaign 3rd District Congressman Russ Carnahan briefly mulled over a run in this district, though the district was more Republican than his previous district, and he did not live in the district. A poll commissioned by Carnahan showed him being competitive with Ann Wagner and Ed Martin. The Democratic Congressional Campaign Committee had preferred that Carnahan run in the district, and considered him a member of the Frontline program for vulnerable members. Ultimately, he ran unsuccessfully for the 1st district.

Primary results Whitfield requested a recount, as the race was separated by less than 1%. By September 13, 2012, the recount was completed and Koenen was declared the winner.
