Oisín Dowling (born 23 June 1997) is an Irish rugby union player, who currently plays for Connacht Rugby. He plays as a lock or flanker.
Dowling attended St Michael's College, Dublin and played alongside fellow Leinster locks Ross Molony and James Ryan there.[1] Dowling spent time in the Leinster sub-academy after leaving schools, before being promoted to the full academy. He was selected for the Ireland U20 team in 2017, a year where they struggled, finishing fourth in the under-20 Six Nations and tenth in the World Championship.
Dowling was part of the Celtic Cup-winning Leinster 'A' side in 2018, a year in which he was also part of Lansdowne's historic clean sweep of the All-Ireland League, All-Ireland Cup, Leinster Senior League and Leinster Senior Cup. Dowling made his senior Leinster debut in January 2019 in a victory against fellow Irish province Ulster.[2]
