Martin Brennan (born 1946) is an Irish hurling coach and former player. At club level, he played with Erin's Own and at inter-county level with the Kilkenny senior hurling team.
Born in Castlecomer, County Kilkenny, Brennan first played hurling as a schoolboy at the local national school and won two county juvenile championship medals. He later lined out at club level with Erin's Own.
At inter-county level, Brennan first played for Kilkenny as a corner-forward on the minor team beaten by Laois in the 1964 Leinster MHC final. He progressed to the under-21 team as a goalkeeper, but ended his underage career without silverware.
Brennan first played for the senior team in a tournament game in December 1966. He scored a goal from corner-forward when Kilkenny beat Tipperary in the 1967 All-Ireland SHC final. Brennan won his first Leinster SHC medal on the field of play two years later. He later claimed a second All-Ireland SHC medal after a 2âÂÂ15 to 2âÂÂ09 win over Cork. Brennan's hurling career ended when he suffered a severe ankle fracture while playing with Kilkenny in New York.
Brennan became involved in team management and coaching following his retirement from playing. He took charge of a number of club teams, including Danesfort, Fenians, Young Irelands and Conahy Shamrocks. Brennan was also a selector on the Kilkenny under-21 team that won the All-Ireland U21HC title in 1990, with his son, Jamesie Brennan, as team captain.
