Randolph County is a county located in the U.S. state of Illinois. As of 2000, the population was 33,893. Its county seat is Chester6.

Owing to its role in the state's history, the county motto is "Where Illinois Began."


According to the U.S. Census Bureau, the county has a total area of 1,547 km² (597 sq mi). 1,498 km² (578 sq mi) of it is land and 49 km² (19 sq mi) of it (3.15%) is water.

The Kaskaskia River flows into the Mississippi River in Randolph County. At this point the Mississippi, which usually defines the border between Illinois and Missouri, is entirely in Illinois. The Mississippi changed its course in the late-nineteenth century, leaving Kaskaskia, the former state capitol, on the west side of the River. The boundary of the State, however, follows the old course of the River, leaving Illinois with an enclave on the western shore of the Mississippi River.

Randolph County was organized in 1795 out of a part of St. Clair County. It was named in honor of Edmund Randolph, Governor of Virginia. The Northwest Territory was captured from the British near the end of the Revolutionary War by the army of Virginia. Illinois then became, for a brief time, Illinois County, Virginia. Edmund Randolph was Governor of Virginia at the time Virginia ceded the Northwest Territory to the United States. The county's boundaries were last changed in 1827, when land was taken to form Perry County.

The Mississippi River has played a prominent role in the county's history, altering its boundaries in 1881 when it severed the isthmus that connected Kaskaskia to the Illinois mainland, destroying the original village of Kaskaskia and forcing its historic cemetery to be relocated across the river to Fort Kaskaskia. Crains Island[1], southeast of Chester, is another enclave of Illinois west of the Mississippi that was created by a change in the river's course.
