John Theophilus Oti Ankrah (25 December 1925 – 28 May 1995), better known as Roy Ankrah, was a Ghanaian featherweight boxing contender during the 1950s. He was given the nicknames "The Black Flash" and "Mr. Perpetual Motion" because of his fast hands and crafty footwork. Ankrah held the Commonwealth featherweight title from 1951 to 1952 and had his biggest fight against then-reigning NBA, NYSAC, and The Ring bantamweight world champion in a non-title fight as both fighters weighed above the 118-pound (54 kg) limit for a bantamweight fighter.
