Highest classical chess ratings ever: Sri Lanka

Peak is a player's highest rating on any of FIDE's classical rating lists since July 1971. When a player reached the same peak more than once, the first month is shown; 'By Jan 2001' means the peak was already on the earliest list we have for that player, so it may be older. Latest is the rating on the most recent list that rates the player. Players are listed under the federation they represent today, with every rating they have held, including ratings held while representing another federation.
