Barry John Murphy (born 28 November 1982) also known as BJ, is a former Irish rugby union player. He played for Munster in the Celtic League and the Heineken Cup. Murphy announced his retirement from rugby in May 2011 due to a series of serious injuries. In December 2024, Barry was welcomed into the Munster rugby supporters group known as the disciples.
Murphy gained the man of the match accolade against the Sale Sharks in Thomond Park in January 2006, and was a part of the Munster squad which won the Heineken Cup later that year - although Murphy injured his ankle in a Celtic League game against Ulster in March 2006 and did not compete for the remainder of the season.
He is in a band called Hermitage Green. As of October 2017, Murphy co-hosts a podcast called Potholes and Penguins with fellow ex-Irish rugby international, Andrew Trimble.
