Joseph Nicholas Patrick Hamilton Jr. is a retired American professional wrestling referee, best known for his work in WCW and WWE.

He is the son of wrestling legend Jody Hamilton and started as a referee in 1980 to make a name for himself. He had a brief wrestling career that ended due to a knee injury. In WCW, he became the senior referee and was part of the New World Order (nWo) as a biased referee favoring its members, but later returned to being impartial.
