William Fitzgibbon (23 May 1878 – 20 May 1955) was an Irish hurler who played as a forward with the Cork senior hurling team.
Fitzgibbon began his hurling career at club level with Carrigtwohill in East Cork.
He enjoyed a lengthy career with the club, however, he never won a Cork Senior Championship title.
At inter-county level, Fitzgibbon first played for the Cork senior hurling team on 3 November 1901 in what was the delayed 1900 championship.
Two years later he won an All-Ireland Championship medal after a 3-13 to no score defeat of London at the Cork Athletic Grounds.
