Patrick J. Riordan (31 August 1871 - March 1941[1]) was an Irish hurler who played as a forward for the Tipperary senior team.[2]
Born in Drombane, County Tipperary, Riordan first arrived on the inter-county scene at the age of twenty-three when he first linked up with the Tipperary senior team. He made his debut during the 1894 championship. Riordan went on to play a key part for Tipperary, and won two All-Ireland medals and two Munster medals.
At club level Riordan was a three-time championship medallist. He began his club career with Drombane before later joining Upperchurch–Drombane and Thurles.
Riordan retired from inter-county hurling following the conclusion of the 1907 championship.
