"Sugar" Ray Seales, (born September 4, 1952) is an American former boxer. He was the only American boxer to win a gold medal in the 1972 Summer Olympics. As a professional, he fought middleweight champion Marvin Hagler three times. He is also the former NABF and USBA middleweight champion.

Seales was born in the U.S. Virgin Islands, where his father, who boxed in the U.S. Army, was stationed. The Seales family moved to Tacoma, Washington in 1965. He is the half-brother of boxer Dale Grant and the brother of boxer Wilbur Seales.

Seales was a product of the Tacoma Boys Club amateur boxing program, and was coached by Joe Clough.

Amateur record: 338–12

Seales was a contender for the middleweight title during the late '70s and early '80s, winning the regional level USBA and NABF titles in the process. In his two most memorable fights, he lost a narrow decision to future middleweight champion Marvin Hagler in July 1974, then drew with Hagler in a rematch three months later. After losing to European champion Alan Minter in 1976, Seales remained on the outskirts of contention, until a first-round technical knockout at the hands of Hagler effectively ended his title hopes.

In 1980, Seales injured his left eye in a fight with Jaime Thomas, and retired due to a serious retinal tear. He was subsequently declared legally blind, and was used as a cause célèbre along with Sugar Ray Leonard during the 1980s for those pushing for a ban on boxing.

Years later, doctors operated and restored Seales' vision in his right eye, though he wears glasses. Seales later worked as a schoolteacher of autistic students at Lincoln High School in Tacoma for 17 years, retiring in 2004. In 2006, he moved to Indianapolis with his wife, and currently teaches at Indy Boxing and Grappling.

Seales was a 2005 inductee into the Tacoma-Pierce County Sports Hall of Fame.
