Casey Creek is a major tributary of the Big Muddy River in Illinois, United States. It is about 39.0 miles (62.8 km) long,[1] measured from the junction of its arm of Rend Lake with the arm formed by the Big Muddy River.

Casey Creek is shown on federal maps as Casey Fork, following a 1967 decision by the U.S. Board on Geographic Names.[2] It is named for Zadok Casey, a congressman from Illinois in the early 19th century.
