The Johnson County Museum of History is a local historical museum located in Franklin, Indiana. The museum is run by the Johnson County Historical Society. The museum officially opened in 1931, under the name "Johnson County Museum." It was organized by the local Chapter of the Daughters of the American Revolution. Originally located in a small room at the county courthouse, the museum has grown over the years, making it necessary to relocate. In 1963 it moved to the Suckow home, and in 1989 it moved again to its current building.
