The 2012 United States House of Representatives elections in Illinois was held on Tuesday, November 6, to elect the 18 U.S. representatives from the state, one from each of the state's 18 congressional districts, 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 quadrennial presidential election. Primary elections were held on March 20, 2012.

Republicans struggled after a strong showing in 2010, losing a total of five seats, one via redistricting, and four via losses by incumbents. Joe Walsh, Bob Dold, Judy Biggert, and Bobby Schilling were all defeated in their bids for re-election. Walsh, Dold, and Schilling had all been elected during the wave year of 2010.

Redistricting A redistricting bill was introduced to the Illinois General Assembly by members of the Democratic Party in May 2011. Although Representatives are not required to live within their districts, the new map drew the homes of at least five Republican incumbents into districts where they would have to run against other Republicans, and others into districts which strongly favor Democrats.

After an amendment which modified the 13th and 15th districts was passed with Republican support, the new map was passed by the Illinois House of Representatives on May 30, 2011 and the Senate on May 31. Governor Pat Quinn, a Democrat, signed the map into law on June 24. Republican members of the congressional delegation planned to mount a legal challenge.
