Buvaisar Hamidovich Saitiev, also spelled Buvaysar Hamidovich Saytiev, (Russian: Бувайсар Хамидович Сайтиев, Chechen: Сайт КIант Бувайса) (born March 11, 1975) is a Russian retired freestyle wrestler of Chechen heritage, who represented Russia, and won nine world-level gold medals in freestyle wrestling (second highest, behind Aleksandr Medved's ten).

[6][7][8] In 1992, Buvaisar left his hometown of Khasavyurt, Dagestan in order to train at a prestigious wrestling center in Krasnoyarsk, Siberia.

Buvaisar's life philosophy has been heavily influenced by Nobel Prize-winning poet Boris Pasternak.

In thirteen years, he competed in eleven World or Olympic championship tournaments, winning nine gold medals at those events and losing only two bouts.

In 1999, Buvaisar did not wrestle at the World championships, instead his weight class was represented by his younger brother Adam Saitiev, who went on to win the gold medal.
