Martin County Courthouse is a historic courthouse in Shoals, Indiana. The courthouse was built in 1876 to replace the previous courthouse, which burned down in the same year. At the time of the courthouse's construction, Shoals had only been the county seat for seven years, and it was the ninth county seat in Martin County.
The new courthouse proved to be in a stable location, as the county seat has remained in Shoals since its construction. The courthouse served the county until 2002 and now houses the Martin County Historical Society's museum.
