Brian Gavin (born 13 July 1977) is an Irish hurling referee.
A native of Clara, County Offaly he is one of the sport's top referees and has officiated at All-Ireland finals in minor, under-21, and the senior final in 2011.
In 2013, he took charge of his second senior final after previously taken charge of the 2011 Final, and also the All-Ireland championship final at minor level in 2004 and under-21 level in 2006. His performance in the 2013 Final was a source of controversy as he played over the time added on thus allowing Clare to score a point to draw the game.
During the 2011 All-Ireland Senior Final, Gavin was accidentally hit by the swinging Hurley of Kilkenny's Tommy Walsh and sustained a nose injury.
Gavin was named as the referee for the 2014 All-Ireland Final replay on 10 September. Gavin was also named as the referee for the 2016 All-Ireland Final.
