Kamarudeen Usman (born May 11, 1987) is a Nigerian American mixed martial artist who competes in the Ultimate Fighting Championship (UFC), where he is the current UFC Welterweight Champion. Usman is also The Ultimate Fighter 21 tournament winner. As of January 27, 2020, he is #7 in the UFC men's pound-for-pound rankings.

Usman was born in Auchi, Nigeria and immigrated with his family to the United States when he was 8 years old. He started wrestling in his sophomore year in high school, at Bowie High School in Arlington, Texas. Because Usman's wrestling coach at the time had trouble pronouncing his first name Kamarudeen, he got the nickname "Marty" when he joined the team and it stuck with him during his amateur wrestling career.

Former National Football League (NFL) star Christian Okoye, who has the nickname "The Nigerian Nightmare" trademarked, gave his blessing for Usman to use it.
