Martijn de Jong (born July 17, 1974) is a Dutch mixed martial artist.

He founded Tatsujin MMA in 1995. After becoming a black belt in Traditional Jiu Jitsu when he was seventeen, he started to master other Martial Arts such as Kyokushin Karate (black belt), Brazilian jiu-jitsu (black belt), Shooto, Dutch Kickboxing, Judo, Wrestling and Submission Fighting.

Because of his technical approach in Mixed Martial Arts during his active fighting career, he was given the nickname ‘The Specialist’ by his manager. When he started his own Team, he called it "Tatsujin Dojo" which means “The Gym of The Specialist” in Japanese.

He started Jiu Jitsu in 1987 at the age of 13. He became a black belt at the age of 17 and started to add Kyokushinkai Karate to become a black belt just 4 years later.
