Illinois elected its United States Representative at-large on a general ticket upon achieving statehood December 3, 1818. Although the practice was first ended in 1830, it was revived several times, so that there would be at least one seat elected at large, in addition to elections in single-member districts. It last elected a US Representative at large in 1946. The district has been obsolete since.

List of members representing the district 1818–1833: one seat

From statehood to 1833, Illinois had only one congressional district, and therefore it was at-large.
