John Charles Campbell (14 September 1867 – 1919) was an American educator and reformer noted for his survey of social conditions in the southern Appalachian region of the United States during the early 1900s.

He graduated from Williams College in 1892 and received a bachelor of divinity degree from Andover Theological Seminary in 1895.

There he outfitted a wagon to serve as a mobile house as he interviewed working people, particularly farmers.

In 1907 he married folklorist Olive Dame of West Medford, Massachusetts.
