Steve Leslie Mahon (born 22 January 1965) is a former Grenadian cricketer who represented the Windward Islands in West Indian domestic cricket. He played as a right-handed middle-order batsman.
Mahon made his first-class debut for the Windwards in January 1986, in a Shell Shield game against Barbados. He made semi-regular appearances for the team into the following decade, in both first-class and one-day competitions, but never established himself in the side for an extended period. In total, Mahon played seventeen first-class and nine List A matches for the Windwards between 1986 and 1993. He never passed fifty in either format, with his highest first-class score being 45 (made against Yorkshire in March 1987) and his highest one-day score being 38 (made against Jamaica in February 1988).
