Joseph Eddy Fontenrose (17 June 1903, Sutter Creek – 7 July 1986, Ashland, Oregon) was an American classical scholar. He was centrally interested in Greek religion and Greek mythology; he was also an expert on John Steinbeck, commenting on the mythology in Steinbeck's work.
He was from Sutter Creek, California. Most of his academic career was spent at University of California, Berkeley, where he had graduated in 1925 in Political Science, after an instructor position he held from 1937. An early influence was Ivan Linforth. He was made a professor in 1955, chaired the classics department, and became professor emeritus.
His politics were known to be socialist. He gave public support in the early 1960s to the Free Speech Movement and Young People's Socialist League. He showed a more conservative side in relation to student activism as it touched teaching.
