Mircea Șimon (born 22 January 1954) is a retired Romanian heavyweight boxer.
He took up boxing in 1971 at Dinamo Bucharest, coached by Constantin Nour, and won a silver medal at the 1976 Olympics,[2] losing to Teófilo Stevenson in the final. Șimon also won four national senior titles and two bronze medals at the European Amateur Boxing Championships.
In 1978 he fled to the United States, where in 1978–1979 he fought 14 bouts as a professional with a record of 12 wins and two draws. He later returned to Romania and coached Marian and Dorel Simion.
He then took a break from boxing for ten years, and in 2007 worked with Romanian Boxing Federation to prepare the national team for the 2008 Olympics.[3]
