Oleg Nikolaevich Taktarov (Russian: Оле́г Никола́евич Такта́ров; born 26 August 1967) is a Russian actor and retired mixed martial artist. He was a practitioner of sambo and judo and competed in the Ultimate Fighting Championship and Pride Fighting Championships. He won the UFC 6 tournament.. He holds notable wins over Marco Ruas, Tank Abbott, Mark Kerr, and Anthony Macias.
Taktarov started his experience in martial arts at 12, when he took up both judo and sambo. He started competing in those disciplines during his obligatory military service, at one point also becoming a hand-to-hand instructor for the KGB, until he retired at 22 in order to become a businessman. However, according to Taktarov, in 1989 he would find himself attracted to a jacketed mixed martial arts event called Jujutsu Full Contact, whose four first editions he won in dominant fashion. He also trained in jujutsu around this time, becoming a four time European champion. In October 1993, Taktarov and a training partner participated in the White Dragon MMA tournament in Latvia, but were forced to flee from the country due to political tensions. He would land in United States, as he planned to pursue a film acting career, though this would be delayed by his lack of fluency in English language.
