Dong Hyun Ma

Kim Dong-hyun (김동현, 金東炫; born September 9, 1988), anglicized as Dong Hyun Kim, also known as "The Maestro", is a South Korean mixed martial artist who most recently competed in the UFC's lightweight division. At the turn of 2019, he began to use the ring name Ma Dong-hyun (anglicized as Dong Hyun Ma; "Ma" as in "Maestro") to better distinguish himself from fellow South Korean mixed martial artist "Stun Gun" Kim Dong-hyun.
