John Arthur Quinn (October 15, 1941 – April 22, 2019) was a Canadian professional wrestler.
He was best known for his appearances in the World Wide Wrestling Federation (WWWF) under the ring name The Kentucky Butcher in the late-1960s, where he challenged then WWWF World Heavyweight Champion Bruno Sammartino on several occasions, including a 1968 main event at Madison Square Garden.
In addition to his appearances in the WWWF, Quinn performed under his birth name for North American regional promotions including NWA All-Star Wrestling, Pacific Northwest Wrestling and Stampede Wrestling from the early 1960s to early 1970s.
During his later career, he also appeared in European and Japanese organizations from the 1970s until the late 1980s.
A popular "heel" in Great Britain during this time, he held the British World Heavyweight Championship a record four times between 1980 and 1986.
