The 14th congressional district of Illinois is currently represented by Democrat Lauren Underwood. It is located in northern Illinois, surrounding the outer northern and western suburbs of Chicago.

Joseph Gurney Cannon, who also served as Speaker of the United States House of Representatives during four congresses and after whom the Cannon House Office Building is named, represented the district early in his career (1873–83), although he was representing the 18th district when he was speaker from 1903 to 1911.

The 14th district was represented from 1987 to 2007 by Republican Dennis Hastert, who served as Speaker of the House during the 106th through 109th Congresses.

Hastert resigned from Congress in November 2007 and on March 8, 2008, the 2008 Illinois's 14th congressional district special election was held to fill the vacancy. Democrat Bill Foster defeated Republican Jim Oberweis by 52.5% to 47.5%. In the November 2008 regular election, Foster won a full two-year term, defeating Oberweis once again. Foster failed to win re-election in 2010. Republican Randy Hultgren won the seat for the GOP and was sworn in when the 112th Congress convened. Hultgren was re-elected in the 2012 election, the 2014 election, and the 2016 election. In the 2018 election, Democratic nominee Lauren Underwood defeated Hultgren, 52.5 to 47.5 percent, thus flipping the Cook Partisan Voting Index Republican +5 district to the Democratic Party.
