Gavin Thornbury

Gavin Thornbury (born 19 October 1993) is an Irish rugby union player who plays as a lock for Utah Warriors in Major League Rugby.

Having completed three years in the Leinster Academy upon leaving Blackrock College, Thornbury earned a professional development contract for the 2015–16 season. However, Thornbury left Leinster to spend six months in New Zealand, where he played for club side Border on the North Island and helped them to victory in the Wanganui premier club competition. This earned Thornbury a call-up to Wanganui provincial representative team, who play in the Heartland Championship - the tier below New Zealand's Mitre 10 Cup and, in October 2016, Thornbury helped Wanganui win the Meads Cup.

Thornbury returned to Ireland and joined western province and then-defending Pro14 champions Connacht on a two-year contract in April 2017.

On 26 September 2024, Thornbury would move to English side Northampton Saints on a short-term deal as injury cover in the Gallagher Premiership for the 2024–25 season.
