Mark Perego (born 8 February 1964 in Winchester, England) is a former Wales international rugby union player.
Perego made his Wales debut 3 March 1990 versus Scotland.
His strengths as a player included his powerful tackling and his phenomenal fitness, the latter of which he maintained through a highly-effective, but eccentric, training regime.
In a famous sequence, BBC Wales filmed him running through a river in a pink beret and chopping trees with an axe.
Perego's nickname was Oddball and he was featured in the 2009 book Rugby's Greatest Characters.
