Yoshinobu Oyakawa (born August 9, 1933) is an American former competition swimmer, Olympic champion, and former world record-holder in the 100-meter backstroke. Oyakawa is considered to be the last of the great "straight-arm-pull" backstrokers and still holds the world record in this technique.
Oyakawa attended the Ohio State University, where he won six Big Ten, seven NCAA, and nine NAAU championships.
He returned to Olympic competition at the 1956 Summer Olympics in Melbourne, Australia, where he was elected co-captain along with Ford Konno. He finished 8th in the 100-meter backstroke competition.
Oyakawa coached at Oak Hills High School from 1960 to 1985. He led Oak Hills to 23 conference championships and was named League Coach of the Year 23 times and Southwest Ohio Swimming Coach of the Year 12 times.
