The Indiana Medical History Museum is an Indianapolis monument to the beginning of psychiatric medical research. It is located on the grounds of what was formerly Central Indiana Hospital for the Insane, later shortened to Central State Hospital. It was placed on the National Register of Historic Places on April 25, 1972, as the Old Pathology Building. It is the United States' oldest surviving pathology laboratory.

Central State Hospital, formally referred to as the Central Indiana Hospital for the Insane, was a psychiatric treatment hospital in Indianapolis, Indiana. The hospital was established in 1848 to treat patients from anywhere in the state, but by 1905, with the establishment of psychiatric hospitals in other parts of Indiana, Central State served only the counties in the middle of the state. In 1950, it had 2,500 patients. Allegations of abuse, funding shortfalls, and the move to less institutional methods of treatment led to its closure in 1994. Since then efforts have been made to redevelop the site for various uses.
