FIDE (Fédération Internationale des Échecs) is the world chess federation, founded in 1924 and recognized by the International Olympic Committee. Its website serves as the official source for player ratings, title norms, event calendars, arbiters' resources, and regulatory documents governing competitive chess worldwide.

The site publishes monthly FIDE rating lists covering millions of rated players globally, organizes the World Chess Championship cycle, and oversees the award of titles from Candidate Master through Grandmaster. It also provides educational resources through its FIDE Trainers Commission and maintains handbooks for tournament organizers and arbiters.

FIDE's website is free to browse. Registered national federations and titled players can access additional member services. For anyone involved in competitive chess — whether tracking ratings, following championship cycles, or understanding official rules — fide.com is the authoritative reference.
