George Rippey Stewart Jr. (May 31, 1895 – August 22, 1980) was an American historian, toponymist, novelist, and a professor of English at the University of California, Berkeley.

His best-known academic work is Names On The Land: A Historical Account of Place-Naming in the United States (1945; reprinted, New York Review Books, 2008).

His scholarly works concerning the poetic meter of ballads (published using the name George R. Stewart, Jr.), beginning with his 1922 Ph.D. dissertation at Columbia, remain important.

Man, An Autobiography is one of the very few works of speculative anthropology, in which he attempts to deduce how major developments of prehistorical civilization must have happened.
