Eino Aukusti Leino (7 April 1891 – 30 November 1986) was a Finnishfreestyle wrestler. He competed at the 1920, 1924, 1928 and 1932 Olympics and won a medal each time, including a gold in 1924.
Leino started as a diver and association football goalkeeper before changing to wrestling. In late 1914 he immigrated to the United States, and therefore did not compete at Finnish, European and world championships until 1930s, when he returned to Finland. He won the American AAU Championships in 1920 and 1923 and placed second in Finnish championships in 1936. Leino was a carpenter by profession, and later in 1949–52 also worked as a sports functionary in Finland.
