John Stanley Hansen II (born August 29, 1949) is an American retired professional wrestler.

Hansen is known for his stiff wrestling style, which he attributes to his poor eyesight. He is also known for his gimmick as a loud, violent cowboy who wanted to fight everybody, which he further emphasized by appearing in interviews with a cowboy hat, leather vest and bullrope while often chewing on tobacco. Considered the most successful and popular gaijin in Japanese professional wrestling history, he became more well-known and revered in Japan than in his native United States. In Japan's AJPW promotion, he held seven different championships. Overall he is a six-time world champion.

In 1989, he played a small role in the movie No Holds Barred and in 2011, released his co-written biography, The Last Outlaw.
