Rhys Davies (9 November 1901 – 21 August 1978) (born Vivian Rees Davies) was a Welsh novelist and short story writer, who wrote in the English language.
One of the most prolific Welsh prose writers of the 20th century, Davies is best known for his short stories, of which he wrote over a hundred. He also wrote eighteen novels, including The Withered Root (1927), The Black Venus (1944) and The Perishable Quality (1957), an autobiography, Print of a Hare's Foot (1969), and a successful play, No Escape (1954), as well as several works of non-fiction. Davies was homosexual, though he never wrote publicly about his own sexuality. Though he lived largely in London, Davies' work is often set in Wales.
Davies was invited to stay with D. H. Lawrence and Frieda Lawrence in France in 1928–9 (their meeting has been dramatised in Sex and Power at the Beau Rivage (2003), a play by Welsh author Lewis Davies). Though Lawrence's death in March 1930 made their friendship a brief one, Lawrence appears to have been an important influence on Davies' work. Other literary associates include the publisher Charles Lahr, who published some of Davies' early work in The New Coterie, and the author Anna Kavan, whose work he edited after her death.
