Sean O'Grady (born February 10, 1959) is a former World Boxing Association lightweight world champion and has worked as a commercial realtor. O'Grady had a record of 81 wins and 5 losses as a professional boxer, with 70 wins by knockout.^[17]

O'Grady was born in Austin, Texas. He is the son of boxing trainer Pat O'Grady and boxing promoter Jean O'Grady. He moved around a lot when he was a child before his family settled in Oklahoma City when he was eleven years old. Pat O'Grady served in the United States Army during World War II.^[14]

O'Grady started boxing professionally in 1975.

He had his last fight in 1983 and retired at the age of twenty four.

In 1980, he had his first world title try when World Boxing Council lightweight champion Jim Watt gave him an opportunity to fight for the title. O'Grady travelled to Glasgow, Scotland to box Watt, but sustained a cut over the forehead due to a head butt late in the bout and lost by a technical knockout in round twelve. The O'Grady's protested the fight's result twenty four hours later while in Republic of Ireland, arguing that the cut had been caused by the headbutt,not a punch. Because of the controversy surrounding the fight, World Boxing Association lightweight champion Hilmer Kenty gave O'Grady another opportunity at the title.They met on April 12, 1981. O'Grady again suffered a cut early in the bout but he dropped Kenty in round eight and won a unanimous decision. The fight was one of the ten best fights of 1981 according to The Ring (magazine).

In part because of problems with his manager/father, he never defended the WBA title and was eventually stripped of it.^[6] Pat O'Grady then formed the lightly regarded and short lived World Athletic Association to recognize Sean as a champion.

O'Grady promptly lost the the World Athletic League Championship title belt to Andrew Ganigan of Hawaii.^[13]

O'Grady served as analyst for television boxing show USA Tuesday Night Fights. The program aired from October 1, 1982 through August 25, 1998 on the USA Network.

He was inducted into the Florida Boxing Hall Of Fame in 2019.^[11] He recieved the "Howie Steindler Award" at the National Boxing Hall of Fame in 2019.^[12]
