John Barrington Wain (14 March 1925 – 24 May 1994) was an English poet, novelist, and critic, associated with the literary group "The Movement". For most of his life, Wain worked as a freelance journalist and author, writing and reviewing for newspapers and the radio.
Wain was born and grew up in Stoke-on-Trent, Staffordshire, the son of a dentist, Arnold Wain, and his wife Annie, née Turner. He had an older sister and a younger brother, Noel. After attending Newcastle under Lyme High School, he entered St. John's College, Oxford, gaining a first in his BA in 1946 and MA in 1950. He was a Fereday Fellow of St John's between 1946 and 1949. On 4 July 1947, Wain married Marianne Uffenheimer (b. 1923 or 1924), but they divorced in 1956. Wain then married Eirian Mary James (1920–1988), deputy director of the recorded sound department of the British Council, on 1 January 1960. They had three sons and lived mainly in Wolvercote, Oxford. Wain married his third wife, Patricia Adams (born 1942 or 1943), an art teacher, in 1989. He died in Oxford on 24 May 1994.
He wrote his first novel Hurry on Down in 1953, a comic picaresque story about an unsettled university graduate who rejects the standards of conventional society. Other notable novels include Strike the Father Dead (1962), a tale of a jazzman's rebellion against his conventional father, and Young Shoulders (1982), winner of the Whitbread Prize, the tale of a young boy dealing with the death of loved ones.
Wain was also a prolific poet and critic, with critical works on fellow Midlands writers Arnold Bennett, Samuel Johnson (for which he was awarded the 1974 James Tait Black Memorial Prize), and William Shakespeare. Among the other writers about whom he has written are the Americans Theodore Roethke and Edmund Wilson. He himself was the subject of a bibliography by David Gerard.
