John Galt (c. 1819–1862) was the first superintendent of the Eastern Lunatic Asylum in Williamsburg, Virginia.
He was a figure in reform of the mental health system in the United States during the mid-19th century.
He advocated for the "moral" treatment of patients as well as music, occupational and recreational therapy.
He could read several languages and synthesized much European research for the American audience with his 1846 book, The Treatment of Insanity.
Galt accepted a small number of free black patients during his tenure as superintendent.
