The men's 200 metres at the 2004 Summer Olympics as part of the athletics program was held at the Athens Olympic Stadium from August 24 to 26. There were 54 competitors from 41 nations. The event was won by Shawn Crawford of the United States, the nation's 17th victory in the men's 200 metres. His teammates Bernard Williams (silver) and Justin Gatlin (bronze) completed the sixth American sweep in the event and first since 1984.
