She was the first woman to receive the Queen's Gold Medal for Poetry in 1955, and was appointed a CBE in 1979 to honour her many contributions to English literature.
In 1974, she was named a "Companion of Literature", the highest honour given by the Royal Society of Literature.
Pitter was born in Ilford. Her birth certificate reports her given name simply as "Ruth."  She was employed at the War Office from 1915 to 1917, later working as a painter at a furniture company in Suffolk, Walberswick Peasant Pottery Co., where she remained until 1930. In Suffolk, she befriended Richard and Ida Blair at Southwold, the parents of George Orwell, and later helped Orwell find lodgings in London in 1927, taking a vague interest in his writing, of which she was generally critical.
Later, Pitter and her lifelong good friend, Kathleen O'Hara, operated Deane and Forester, a small firm that specialized in decorative, painted furniture. The business closed when World War II began. Pitter took work in a factory. After the war, she and O'Hara opened a small business painting trays. Pitter was skilful at the flower-painting used in both furniture and tray decorating.
Pitter began writing poetry early in life under the influence of her parents, George and Louisa (Murrell) Pitter, both primary schoolteachers. In 1920, she published her first book of poetry with the help of Hilaire Belloc. Despite her business and factory work, Pitter managed to spend a few hours a day writing poetry.
She went on to publish 18 volumes of new and collected verse over a 70-year career as a published poet. Many of her volumes met with some critical and financial success.
Style and influences
Pitter was a traditionalist poet—she avoided most of the experimentations of modern verse and preferred the meter and rhyme schemes of the 19th century. One critic has described her and her poetry thus:
Pitter, in contrast to T. S. Eliot, Ezra Pound, and W. H. Auden, is a traditional poet in the line of George Herbert, Thomas Traherne, Thomas Hardy, A. E. Housman, W. B. Yeats, and Philip Larkin. Unlike the modernists, she rarely experiments with meter or verse form, nor does she explore modernist themes or offer critiques of modern English society. Instead, she works with familiar meters and verse forms, and her reluctance to alter her voice to follow in the modernist line explains in part why critics have overlooked her poetry. She is not trendy, avant-garde, nor, thankfully, impenetrable.— Don King, "The religious poetry of Ruth Pitter," Christianity and Literature, June 22, 2005
Because of this, Pitter was frequently overlooked by critics of her day, and has only in recent years been seen as important: her reputation was helped by Larkin's respect for her poetry (he included four of her poems in The Oxford Book of Twentieth Century English Verse).
She was a good friend of C. S. Lewis, who admired her poetry and once said, according to his friend and biographer George Sayer, that if he was the kind of man who got married, he would have wanted to marry Ruth Pitter. In correspondence between the two, Lewis often critiqued her work and made suggestions. More often he invited her critique of his poems. Pitter is considered by many Lewis scholars to have had an effect on his writing in the 1940s and 1950s.
Pitter's work continues to be published in anthologies, including:
- The Faber Book of 20th Century Women's Poetry, ed. Fleur Adcock (London: Faber & Faber, 1987), where her "The Sparrow's Skull" and "Morning Glory" appear (pp. 77–78).
- More Poetry Please! 100 Popular Poems from the BBC Radio 4 Programme (London: Everyman, 1988), where her "The Rude Potato" appears (pp. 101–02).
- The Oxford Book of Garden Verse, ed. John Dixon Hunt (Oxford: Oxford University Press, 1993), where her "The Diehards" and "Other People's Glasshouses" appear (pp. 236–41).

- The New Penguin Book of English Verse, ed. Paul Keegan (London: Allen Lane, Penguin Press, 2000), where her "But for Lust" appears (p. 962).
Christian faith influences
Pitter described her spiritual debt to C. S. Lewis:
As to my faith, I owe it to C. S. Lewis. For much of my life I lived more or less as a Bohemian, but when the second war broke out, Lewis broadcast several times, and also published some little books (notably "The Screwtape Letters"), and I was fairly hooked. I came to know him personally, and he came here several times. Lewis's stories, so very entertaining but always about the war between good and evil, became a permanent part of my mental and spiritual equipment.— Letter, Ruth Pitter to Andrew Nye, dated 18 May 1985.
Did I tell you I'd taken to Christianity? Yes, I went & got confirmed a year ago or more. I was driven to it by the pull of C. S. Lewis and the push of misery. Straight prayer book Anglican, nothing fancy [...] I realize what a tremendous thing it is to take on, but I can't imagine turning back. It cancels a great many of one's miseries at once, of course: but it brings great liabilities, too.— Letter, Ruth Pitter to Nettle Palmer, dated 1 January 1948.
