Peter O'Reilly (29 September 1902 – 25 February 1940) was an Irish hurler who played as a full-back for the Kilkenny senior team.
O'Reilly made his senior inter-county debut for Kilkenny in a National League defeat by Dublin on 26 March 1926.
Although he missed Kilkenny's subsequent championship defeat of Dublin, O'Reilly was named at full-back for the provincial decider.
Controversy and dissent dogged the game as O'Reilly and his teammates from the Dicksboro club did not play as they disagreed with the selection committee's choice.
It was also suggested at a meeting of Central Council that both teams be declared joint champions and that half an All-Ireland medal by given to each player.
As the All-Ireland saga went to a third meeting on 1 November 1931, Kilkenny captain Lory Meagher was ruled out of the game because of broken ribs sustained in the first replay.
[2] Kilkenny retained their provincial crown in 1932, with O'Reilly adding a third Leinster medal to his collection following a 4-6 to 3-5 defeat of Dublin.
The All-Ireland final on 3 September 1933 saw a record crowd of 45,176 travel to Croke Park to see Kilkenny face and up-and-coming Limerick.
After being level at the interval, the game remained close in the second half until a solo-run goal by Johnny Dunne sealed a 1-7 to 0-6 victory.
At the beginning of the second-half Lory Meagher sent over a huge point from midfield giving Kilkenny a lead which they wouldn't surrender.
Kilkenny dominated the provincial series again in 1936 and O'Reilly won his sixth Leinster medal following a 4-6 to 2-5 defeat of Laois.
