The Wabash County Courthouse is a historic governmental building in downtown Mount Carmel, Illinois, United States.
Built in the late nineteenth century as the fifth courthouse in Wabash County, it has experienced a series of extensive remodelling projects that have left it with virtually nothing of the original building.
County commissioners contracted with miller Moses Bedell in September 1825 for the construction of a frame courthouse, two stories tall and measuring 26 by 36 feet (7.9 m × 11.0 m).
