Brian Thomas O'Halloran (born 17 May 1991) is an Irish hurler and Gaelic footballer who plays for Waterford Championship club Clashmore–Kinsalebeg.
He had already broken onto the club's top adult team when he captained Clashmore to the Waterford Minor Championship title in 2009.
A series of hamstring and ankle ligament injuries stunted his progression, however, he made a combined total of 47 National League and Championship appearances in a career that ended with his last game in 2019.
On 20 May 2009, he captained the team and scored 1-04 from centre-forward when Clashmore defeated Ballinacourty by 1–07 to 1–06 to win the Waterford Minor Football Championship.
After returning to the panel in 2012, O'Halloran tore ligaments in his ankle and missed the entire season for a second successive year.
"[13] On 3 May 2015, O'Halloran was named at right corner-forward but started the game on the bench when Waterford faced Cork in the National League final.
[14] On 12 July 2015, O'Halloran was an unused substitute when Waterford were beaten for the fourth time in six seasons by Tipperary in the 2015 Munster final.
[15] On 1 May 2016, O'Halloran was introduced as a 63rd-minute substitute for Austin Gleeson when Waterford drew 0-22 apiece with Clare in the National League final.
