Funks Grove is a historic unincorporated community on U.S. Route 66 in McLean County, Illinois, United States, southwest of Bloomington.

[2] Due to fire suppression, the makeup of tree life in Funk's Grove is changing from historic times, with the original oaks not reproducing themselves naturally.

In addition, a rest stop lies on the edge of the grove on Interstate 55 at Illinois Milepost 149.

Funks Grove Nature Spaces opened in October 2004 and is run by a non-profit organization.

Originally called Sugar Grove Nature Center, it was renamed in April 2024.
