Florencio Campomanes (born 1927) is a Filipino chess player and organiser.

He represented his country at several Chess Olympiads, and met some distinguished opposition as a result, losing games against Pal Benko and Ludek Pachman at Moscow 1956, Oscar Panno at Munich 1958, Mikhail Tal and Miguel Najdorf at Leipzig 1960 and Lev Polugaevsky at Havana 1966.

He is best remembered, however, as the President of international chess organisation FIDE. He took the post in 1982 and held it through several controversies, most notably the abandonment of the 1984 World Championship between Anatoly Karpov and Garry Kasparov without result, and the break-away from FIDE of the Professional Chess Association in 1993.

Campomanes was succeeded as FIDE President in 1995 by Kirsan Ilyumzhinov.
