Roger Petit (born 17 August 1922) is a Belgian Olympic fencer. He competed in the team sabre event at the 1960 Summer Olympics. The 1960 Summer Olympics, officially known as the Games of the XVII Olympiad, was an international multi-sport event held from August 25 to September 11, 1960 in Rome, Italy. Rome had been awarded the organization of the 1908 Summer Olympics, but after the 1906 eruption of Mount Vesuvius, was forced to decline and pass the honors to London. On June 15, 1955, at the 50th IOC Session in Paris, France, Rome beat out Lausanne, Detroit, Budapest (being the first city of the Eastern Bloc to bid for the hosting of the Olympics), Brussels, Mexico City and Tokyo for the rights to the Games.
