Philip O'Dwyer (1934 – 27 September 2020), commonly known as Billy Dwyer, was an Irish hurler whose career included two All-Ireland Championship victories with the Kilkenny senior hurling team.
Born in Kilkenny, Dwyer first played competitive hurling during his schooling at St. Patrick's De La Salle.
[2] As a member of the Leinster inter-provincial team on a number of occasions, Dwyer was a one-time Railway Cup medallist.
Dwyer joined the Kilkenny senior team in advance of the 1956 Leinster Championship and made his debut on 20 May 1956 when he scored two goals from full-forward in a 6–11 to 3-09 quarter-final win over Westmeath.
Dwyer lined out in a second successive Leinster final on 4 August 1957 and claimed his first winners' medal after scoring 1–02 in the 6–09 to 1–05 defeat of Wexford.
Dwyer missed the 1959 Leinster Championship, however, he was recalled to the starting fifteen at full-forward for the All-Ireland final against Waterford on 6 September 1959.
The replay on 4 October 1959 saw Dwyer again line out at full-forward, however, in spite of top-scoring with five points he ended the game on the losing side after the 3–12 to 1–10 defeat.
