Osamu Watanabe (渡辺 長武, Watanabe Osamu, born on October 21, 1940) is a retired Japanese freestyle wrestler. In 1962, he debuted internationally and retired shortly after the 1964 Olympics. During his brief career Watanabe won all his few hundred bouts without losing a single point. This achievement remains unmatched in any type of competitive wrestling, as reflected in the Guinness World Records.
In the early 2000s Watanabe resumed competing internationally in the masters category.
