Gerald Mulcahy (1934 – 9 November 1994) was an Irish hurler who played at club level with Glen Rovers and at inter-county level with the Cork senior hurling team. He usually lined out as a defender.

Mulcahy first came to prominence as a hurler with the Glen Rovers club on Cork's northside. He was only 16-years-old when he won a Cork JHC title in 1950. He later won a Cork SHC title with the senior team in 1959, having already won a Cork SFC with sister club St. Nicholas' in 1954. Mulcahy was a dual player when he first appeared on the inter-county scene at minor level. He was a reserve when Cork won the All-Ireland MHC in 1951 before winning a Munster MFC title in 1952.^[1][2] Mulcahy won an All-Ireland JHC title in 1955 and was one of seven players who made their senior team debut when Cork were beaten by Waterford in the 1959 Munster final.^[3][4]

Mulcahy died suddenly at the Mercy Hospital on 9 November 1994. His son, Tomás Mulcahy, captained Cork to victory in the 1990 All-Ireland final.^[5]
