Léonel Saint-Preux (born February 12, 1985) is a Haitian former professional footballer who played as a forward.

Saint-Preux began his career with Haitian club Zénith, where he was generally regarded as one of the most promising footballing talents in the Ligue Haïtienne.

In early March 2010 he pre-signed a two-year contract with the Aztex, against whom he made his USL debut in 2009, but he was released before the season started after failing his medical.

He was a member of Haiti's qualifying squad for the 2008 Beijing Olympics, scoring a memorable 40 yard goal in his nation's 2–1 victory over Canada.

He debuted for the full Haitian national team in 2007, and has since participated in several World Cup qualifying matches.
