Olivier Peslier (born 12 January 1973 in Château-Gontier) is a French thoroughbred horse racing jockey.
Peslier competes in flat racing mainly in France but travels often around the world for the big international races. From 2003 to 2014, he was a retained jockey for the Wertheimer et Frère horse racing and breeding business partnership of brothers Alain and Gérard Wertheimer of France. In his free time, Peslier plays paintball, an unusual hobby for a jockey.
