Illinois Route 13 (IL 13) is a major east–west state route in southern Illinois. Illinois 13 has its western terminus at Cahokia Heights at Illinois Route 157 and its eastern terminus at the Kentucky state line and the Ohio River, at Kentucky Route 56. This is a distance of .

Another reroute took place between 1944 and 1947 when Illinois 13 took over a new highway (then called U.S. Route 460) in and around Belleville. The old route became Alternate Illinois 13. In 1947 it was moved back to Bond Avenue. Later, U.S. 460 would be dropped and replaced with Illinois Route 15. In October 2010, the first section of the bypass opened on the north side of Harrisburg, between Illinois Route 34 and U.S. 45, and IL 34 was rerouted on this portion of the bypass. The remaining section of the bypass west of IL 34, replacing IL 13's former route along busy Poplar Street, opened in April 2012.
