Raimundo Bibiani "Mumo" Orsi (December 2, 1901 – April 6, 1986) was an Italian Argentine footballer who won the 1934 FIFA World Cup with Italy and the silver medal at the 1928 Summer Olympics in Amsterdam, Netherlands.
His career began in Argentina with Club Atlético Independiente (1920–1928; 1935), but it was with Juventus that Orsi would have the most success in his club career. He joined the club in time for the 1928-29 season and would stay at Juventus until 1935, winning five consecutive league titles in 1931, 1932, 1933, 1934 and 1935. After leaving Italy, Orsi played the rest of his career in South America. He returned to Independiente before moving on to Boca Juniors, Club Atlético Platense and Almagro he also played for Peñarol in Uruguay, Flamengo in Brazil and Santiago National in Chile.
His international debut for Argentina on August 10, 1924 was against Uruguay. Over the next 12 years, he played 13 times for Argentina and scored 3 goals. Orsi's career is strange by modern standards, however, in that he played for Italy as well as Argentina, allowing him to gain 35 caps and score 13 goals for his second country between December 1, 1929 and March 24, 1935. This also allowed him to be a part of the side that won the 1934 World Cup, in the final of which he scored. He died in 1986 aged 84.
