Cecil Day-Lewis (or Day Lewis), CBE (27 April 1904 – 22 May 1972) was an Irish poet and the Poet Laureate of the United Kingdom from 1968 until his death in 1972. He also wrote mystery stories under the pseudonym of Nicholas Blake. He is the father of actor Daniel Day-Lewis and documentary filmmaker and television chef Tamasin Day-Lewis.
In his autobiography The Buried Day (1960), he wrote "As a writer I do not use the hyphen in my surname – a piece of inverted snobbery which has produced rather mixed results . . . ." (p.17)
Day-Lewis was born in Ballintubbert, Stradbally, Queen's County (now known as County Laois), Ireland. He was the son of the Reverend Frank Cecil Day-Lewis (died 29 July 1937) and Kathleen Blake (née Squires; died 1906). After the death of his mother in 1906, Cecil Day-Lewis was brought up in London by his father, with the help of an aunt, spending summer holidays with relatives in County Wexford. He continued to regard himself as Anglo-Irish for the remainder of his life, though after the declaration of the Republic of Ireland in 1948 he chose British rather than Irish citizenship, on the grounds that 1940 had taught him where his deepest roots lay. He was educated at Oundle School and at Wadham College, Oxford. In Oxford, Day-Lewis became part of the circle gathered around W. H. Auden and helped him to edit Oxford Poetry 1927. His first collection of poems, Beechen Vigil, appeared in 1925. 
In 1928 he married Constance Mary King, the daughter of a Sherborne master (i.e. teacher), and worked as a schoolmaster in three schools. During the 1940s he had a long and troubled love affair with the novelist Rosamond Lehmann. His first marriage was dissolved in 1951, and he married actress Jill Balcon, daughter of Michael Balcon.
During the Second World War he worked as a publications editor in the Ministry of Information, an institution satirised by George Orwell in his dystopian Nineteen Eighty-Four, but equally based on Orwell's experience of the BBC. During the Second World War his work was now no longer so influenced by Auden and he was developing a more traditional style of lyricism. Some critics believe that he reached his full stature as a poet in Word Over All (1943), when he finally distanced himself from Auden. After the war he joined the publisher Chatto & Windus as a director and senior editor.
In 1946, Day-Lewis was a lecturer at Cambridge University, publishing his lectures in The Poetic Image (1947). He later taught poetry at Oxford, where he was Professor of Poetry from 1951 to 1956. During 1962–1963, he was the Norton Professor at Harvard University. He was appointed Poet Laureate in 1968, in succession to John Masefield.
Day-Lewis was chairman of the Arts Council Literature Panel, vice-president of the Royal Society of Literature, an Honorary Member of the American Academy of Arts and Letters, a Member of the Irish Academy of Letters and a Professor of Rhetoric at Gresham College, London.
Cecil Day-Lewis died from pancreatic cancer on 22 May 1972, aged 68, at the Hertfordshire home of Kingsley Amis and Elizabeth Jane Howard, where he and his wife were staying. He was a great admirer of Thomas Hardy, and had arranged to be buried as close as possible to the author's grave in Stinsford churchyard.  Day-Lewis's epitaph reads:
"Shall I be gone long?
For ever and a day
To whom there belong?
Ask the stone to say
Ask my song"
Day-Lewis's two marriages yielded four children, including Academy Award-winning actor Daniel Day-Lewis, food writer and journalist Tamasin Day-Lewis, and TV critic and writer Sean Day-Lewis, who wrote a biography of his father, C. Day Lewis: An English Literary Life (1980).
In his youth Day-Lewis adopted communist views, becoming a member of the Communist party from 1935 to 1938, and his early poetry was marked by didacticism and a preoccupation with social themes. In 1937 he edited The Mind in Chains: Socialism and the Cultural Revolution. In the introduction he supported a popular front against a "Capitalism that has no further use for culture". He explains that the title refers to Prometheus bound by his chains, quotes Shelley's preface to Prometheus Unbound and says the contributors believe that "the Promethean fire of enlightenment, which should be given for the benefit of mankind at large, is being used at present to stoke up the furnaces of private profit". The contributors were: Rex Warner, Edward Upward, Arthur Calder-Marshall, Barbara Nixon, Anthony Blunt, Alan Bush, Charles Madge, Alistair Brown, J. D. Bernal, T. A. Jackson and Edgell Rickword. After the late 1930s he gradually became disillusioned with communism. Among his works is his autobiography, Buried Day (1960), in which he renounces his communist views, while his detective story, The Sad Variety (1964), contains a scathing portrayal of doctrinaire communists, the repression of the 1956 Hungarian uprising, and the ruthless tactics of Soviet intelligence agents
