Gérald Mossé (born 3 January 1967 in France) is a jockey in thoroughbred horse racing. He began riding professionally in April 1983 and his success during his apprenticeship under Patrick-Louis Biancone led to an offer to ride for renowned trainer François Boutin and his stable of horses belonging to Jean-Luc Lagardère. Mossé went on to become one of his country's top jockeys, winning the 1990 Prix de l'Arc de Triomphe. In 1991, he rode Arazi to five straight wins in France then spent 1992 and part of 1993 racing in Hong Kong.
From 1993 to late 2001, Gérald Mossé was the principal rider for the horses belonging to the Aga Khan IV. He then returned to live and race in Hong Kong (where he is also known in Chinese as 巫斯義) but continues to ride in major European and international races.
