Idris Davies (1905–1953) was a Welsh poet who originally wrote in Welsh but later wrote exclusively in English.
He was the only poet to cover significant events of the early 20th century in the South Wales Valleys and the South Wales Coalfield and from a perspective literally at the coalface. He is now best known for the verses "Bells of Rhymney", from his 1938 Gwalia Deserta (meaning literally "Wasteland of Wales"), which were later adapted into a popular folk song.
