Ben Austin Blair (born 26 March 1979 in Westport, New Zealand) is a former rugby union footballer. He played four tests for New Zealand. He scored 37 points on his All Blacks debut against Ireland A in 2001 at Ravenhill in Belfast; however, as this was not a test match he was not capped. His first test match appearance came in November that year against Scotland. In 2012, Blair joined French club SU Agen Lot-et-Garonne of the Top 14; however, he was forced to retire due to a knee injury without playing a single game for the side.
