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 was built with local sandstone and red brick; its design incorporates elements of the Greek Revival and Italianate styles.
