The 3rd Illinois General Assembly, consisting of the Illinois State Senate and the Illinois House of Representatives, met from December 2, 1822, to February 18, 1823, during the first two years of Edward Coles' governorship, at The Vandalia State House. The apportionment of seats in the House of Representatives was based on the provisions of the First Illinois Constitution. Political parties were not established in the State at the time.
The 3rd General Assembly was preceded by the 2nd Illinois General Assembly, and was succeeded by the 4th Illinois General Assembly.
This list is arranged by chamber, then by county. Senators and Representatives were both allotted to counties roughly by population and elected at-large within their districts.
Legislation passed on February 14, 1821 fixed the Senate at 18 members and the House at 36 members; and established apportionment by county.
Six new counties were added in 1821: Lawrenece, Greene, Sangamon, Hamilton, and Montgomery.
