James Loughlin "Locky" Byrne (28 April 1913 – 18 January 1941) was an Irish hurler who played as a full-forward for the Kilkenny and Waterford senior teams. Born in Waterford, Byrne first arrived on the inter-county scene at the age of fifteen when he first linked up with the Waterford minor team, before later joining the senior side. He made his senior debut during the 1931 championship. Byrne immediately became a regular member of the starting fifteen, before later playing with Kilkenny, and won one All-Ireland medal, one Leinster medal and one Munster medal. He was an All-Ireland runner-up on two occasions.
