Nathan Sharpe (born 26 February 1978) is a retired professional Australian rugby union player.

He began his rugby career at the Queensland Reds in 1999 before joining the newly created Western Force in 2006, where he captained the club until his retirement in 2012.

It was the first year of professional rugby and the team included Wallabies John Eales and Garrick Morgan.

Sharpe's presence in the second row took on added importance in the absence of the injured James Horwill, and he captained the side for the remainder of the year.

[7] Nathan is married to ex-Sydney Swifts netball player, Samantha Sharpe (née Dennis).
