Abraham Moses Klein (14 February 1909 – 20 August 1972) was a Canadian poet, journalist, novelist, short story writer and lawyer. He has been called "one of Canada's greatest poets and a leading figure in Jewish-Canadian culture." Best known for his poetry, Klein also published one novella entitled The Second Scroll in 1951, along with numerous essays, reviews, and short stories. Many of his lesser-known works, including several unfinished novels, were published posthumously in a series of collections from the University of Toronto Press.
