Lewis Davies (18 May 1863 – 18 May 1951) was a Welsh writer and schoolmaster. He was from the Hirwaun area of Aberdare, Glamorgan (now Rhondda Cynon Taf), where his father worked as a refiner at Crawshay Ironworks. He attended Penderyn Elementary School and, when old enough, became a pupil teacher before winning a scholarship to Bangor Normal College, which he attended from 1881 to 1882. When he returned to Hirwaun, he took up the position of headmaster of the local school (from 1884 to 1886), and he then became headmaster of Cymmer School in the Afan Valley, remaining there until he retired in 1926.
