Chris Whitaker is an Australian professional rugby union coach and former international player. He began his professional playing career in 1997 as a scrum-half for the Waratahs, where he remained for ten seasons. He also played for the Wallabies, but his Test career there was constrained for many years by the incumbent scrum-half and Australian captain, George Gregan. As such, he got minimal international game time but was in the match-day squad for many a year. He captained the Wallabies in a World Cup Match against Namibia in Adelaide in 2003. In 2006, Whitaker moved to Ireland where he played four seasons for Leinster before retiring and taking up coaching.

As of 2018, he is head coach of the Sydney Rays in Australia's National Rugby Championship, and the interim head coach of Super Rugby side the New South Wales Waratahs.
