Douglas Valentine LePan (25 May 1914 - 27 November 1998) was a Canadian diplomat, poet, novelist and professor of literature.

Born in Toronto, Ontario, LePan joined the Canadian diplomatic service in 1946 and remained with the Department of External Affairs until 1959. He subsequently taught at Queen's University, Kingston, Ontario, and the University of Toronto where he was University Professor and Senior Fellow at Massey College. His wartime experience with the Canadian Army in Italy inspired his poetry and one novel The Deserter (1964). LePan is the only person ever to have won the Governor General's award for poetry and fiction. He was made an Officer of the Order of Canada in 1998. A much anthologized poem is A Country Without a Mythology.

LePan was awarded the Royal Society of Canada's Lorne Pierce Medal in 1976.
