Roger Anthony Black MBE is an English former athlete who competed internationally for Great Britain and England. During his athletics career, he won individual silver medals in the 400 metres sprint at both the Olympic Games and World Championships, two individual gold medals at the European Championships, and 4 × 400 metres relay gold medals at both the World and European Championships.

The 4 × 400 metres relay or long relay is an athletics track event in which teams consist of four runners who each complete 400 metres or one lap. It is traditionally the final event of a track meet. At top class events, the first leg and the first bend of the second leg are run in lanes. Start lines are thus staggered over a greater distance than in an individual 400 metres race; the runners then typically move to the inside of the track. The slightly longer 4 × 440 yards relay, on an Imperial distance, was a formerly run British Commonwealth and American event, until metrication was completed in the 1970s.
