Lucian Popescu (12 January 1912, in Bucharest – 9 December 1982) was a Romanian boxer who won European titles in three different classes. Nicknamed Chocolate Boy ("băiatul de ciocolată"), he is considered to be the best Romanian boxer between the two world wars. Making his amateur debut on 23 December 1927, he became national champion in the flyweight class in 1928. When he was 17, he decided to turn pro and won his first match against a German boxer. He died on 9 December 1982.
