Warren Crawford Cowgill (/ˈkoʊɡɪl/ KOH-gill;[1] December 19, 1929 – June 20, 1985) was an American linguist.

Cowgill was unusual among Indo-European linguists of his time in believing that Indo-European should be classified as a branch of Indo-Hittite, with Hittite as a sister language of the Indo-European languages, rather than a daughter language.

Along with his brother, he graduated from Stanford University in 1952 and received a Ph.D. from Yale in 1957.

He was a member of the Yale faculty in the Department of Linguistics until his death in 1985.
