The 1986 World Chess Championship was played between Anatoly Karpov and Garry Kasparov in London and Leningrad (Saint Petersburg) from July 28 to October 8, 1986. Games 1-12 were played at the Park Lane Hotel, Piccadilly, London, and games 13–24 at the Hotel Leningrad. Anatoly Karpov was already assured of this rematch during his previous year's match, which was won by Garry Kasparov.

The rematch had been demanded by Florencio Campomanes, President of FIDE, citing a ruling introduced in 1978. Kasparov initially refused and, for the first time, threatened to divide the chess world by seceding from FIDE. However, the match was finally held after an agreement between the two players. Kasparov won with 12.5 to 11.5 points, thus defending his title of World Champion.

This match was the first world championship between two Soviets to take place outside of Moscow. The match would be won by the player who got the best of 24 games. Kasparov taking a lead in game 8 and maintained it until Karpov consecutively won games 17, 18 and 19
