Glyn Davies (24 August 1927 – 7 November 1976) was a Welsh international rugby union fly-half who played club rugby for a large selection of clubs but most notably for Pontypridd and Cambridge University. He won eleven international caps for Wales including a win over the touring 1947 Australia team. Described as a mercurial outside half, Davies was notable for his sidestep and ability to change pace and direction with ease. He was the brother-in-law of Welsh opera singer Sir Geraint Evans.
