The 7th congressional district of Illinois covers parts of Cook County, as of the 2023 redistricting that followed the 2020 census.

With a Cook Partisan Voting Index rating of D+36, it is the most Democratic district in Illinois.

[citation needed] In 1846, the 7th district was the only one in Illinois (among seven at the time) with a comfortably safe majority for the Whig Party.

[3] As of the 2020 redistricting, this district will still be primarily based in Chicago's Central-South-West Side, as well as central Cook County.

The 7th district takes in the Chicago neighborhoods of the Loop, Armour Square, Fuller Park, Near West Side, East Garfield Park, West Garfield Park, North Lawndale, and West Englewood; most of Near South and Austin; half of Humboldt Park and Englewood; the coastal portion of Near North; part of West Town, Douglas, Grand Boulevard, and Chicago Lawn.
