Jim Miller Bio

Jim Miller is an American mixed martial artist competing in the UFC lightweight division. As of September 14, 2026, the UFC lists him as active and training at Miller Brothers MMA in Sparta, New Jersey. Born August 30, 1983, Miller is 5 feet 8 inches tall and is known by the nickname “A-10.”

Miller turned professional in 2005 and made his Octagon debut at UFC 89 on October 18, 2008. His long UFC tenure includes appearances at UFC 100, UFC 200 and UFC 300. In May 2026, he defeated Jared Gordon by guillotine submission at UFC 328, reinforcing the submission-based identity that has defined much of his career.

A southpaw with a wrestling foundation, Miller is principally identified as a jiu-jitsu fighter. The UFC notes that he received his Brazilian jiu-jitsu black belt from Jamie Cruz in July 2010. His game is built around pressure, clinch-and-grapple exchanges, top control and opportunistic submission attacks, while his durability and willingness to compete frequently have made him one of the defining UFC lightweights of his era.
