Mitchell is an unincorporated community and census-designated place (CDP) in Madison County, Illinois, United States.

It is bordered to the south and east by Pontoon Beach, to the northeast by Edwardsville, and to the northwest by the unincorporated community of Brooks.

A few years ago, Mitchell tried to become an independent city, but that vote was never allowed because of court challenges from nearby communities.

[citation needed] According to the U.S. Census Bureau, the Mitchell CDP has an area of 0.56 square miles (1.45 km2), all land.

Near town to the east is the Gateway Commercial Business Center, a place of trucking companies and more.
