Donald Johnson Greene (November 21, 1914 – May 13, 1997) was a literary critic, English professor, and scholar of British literature, particularly the eighteenth-century period.
Known especially for his work on Samuel Johnson, he also wrote on later authors such as Jane Austen, Evelyn Waugh, Graham Greene, and Donald Davie.
He began teaching in rural elementary schools and was a non-degreed teacher in Saskatchewan and Alberta.
World War II interrupted his academic pursuits; from 1941 to 1945 Greene was a lieutenant and captain in the Royal Canadian Artillery.
He ended his career as Leo S. Bing Professor of English at the University of Southern California from 1968 to 1984.
