John Kearsley Mitchell (May 12, 1798 – April 4, 1858) was an American physician and writer, born in Shepherdstown, Virginia (present-day West Virginia). Orphaned at the age of eight, and sent to his late father's family in Scotland at the age of thirteen, Kearsley was educated at Ayr Academy and the University of Edinburgh.

He returned to the United States in 1814, and began studying medicine under Dr. Samuel Powel Griffitts (apprenticeship was a common method of medical education in this period) before enrolling at an institution for his medical education.
