Olivier Claude C. Magne (born 11 April 1973 in Aurillac, Cantal) is a French former rugby union footballer and a current coach.

Magne was a rugby back row forward, known especially for his speed and handling in open field play.

The highlight of his career was probably the 1999 Rugby World Cup final, where he ended on the losing side as France were beaten 35–12.

Magne played in the mid-year Tests against South Africa and Australia but missed the November internationals through injury.

On 9 November 2009 the Greek Rugby Federation announced that Magne would be taking over as the new coach of the Greece national team.
