Nils Schumann (born 20 May 1978) is a former German athlete, winner of the 800 m at the 2000 Summer Olympics, who retired in 2009. For most of the five years before his retirement he had featured sparingly at an international level due to injuries.
He also made the final of the 1999 World Athletics Championships, but placed 8th and last. He had a quiet 2000 season, until the Olympics started in Sydney. Schumann cruised through the preliminaries, easily qualifying for the final. In the final, Schumann set in his final sprint at the last straight, taking the lead with just 50 m to go. Favourite Wilson Kipketer of Denmark gained in the closing meters, but was unable to prevent a surprise victory by the German runner. In the following year, Schumann finished in fifth place at the 2001 World Championships in Athletics in Edmonton.
