2014 Cook County Board of Commissioners election

The 2014 Cook County Board of Commissioners election was held on November 4, 2014. It was preceded by a primary election held on March 18, 2014. It coincided with other 2014 Cook County, Illinois, elections (including the election for president of the Cook County Board of Commissioners). It saw all seventeen seats of the Cook County Board of Commissioners up for election to four-year terms.

Fifteen members were reelected. One member did not seek reelection and one member was defeated in their party's primary, which meant that a total of two individuals were newly elected. The Democratic Party ran nominees for fifteen of the seventeen seats, while Republicans ran nominees for only five of the seats.

As these were the first elections held following the 2010 United States Census, the seats faced redistricting before this election.

Democrats ran nominees in races for fifteen of the seventeen seats. Republicans ran nominees in races for five seats. In races for twelve seats, Democratic nominees faced no opponents on the ballot. In races for two seats, Republican nominees faced no opponents on the ballot. As a result, only three general election races were contested between Democratic and Republican nominees.
