Berkshire Medical College (originally the Berkshire Medical Institution, and sometimes referred to as Berkshire Medical College) was a medical school in Pittsfield, Massachusetts. It is notable for establishing the first professorship in mental diseases at any medical school in the United States, and for granting the first medical degree ever issued to an African American. It originated in 1823 as the Medical Department of Williams College, graduated 1138 people, and was disbanded in 1867.
