John Ethan Wayne (born February 22, 1962), better known by his stage name Ethan Wayne, is an American actor, son of actor John Wayne and his third wife Pilar Pallete Wayne. Ethan grew up in Newport Beach, where he shared his father's love of the ocean and outdoors. His name was chosen in direct relation to John Wayne's character in The Searchers, Ethan Edwards.

He played Little Jake, the grandson of his father's title character in Big Jake. Ethan started doing stunt work after the death of his father in 1979. His first film was The Blues Brothers. He then went back to work as an actor. His next two major film appearances were in 1981, in the comedy Longshot, and the slasher film Scream. Later works included a role, in the NBC TV movie The Alamo: 13 Days to Glory, as Edward Taylor in 1986, Storm Logan on the CBS soap opera The Bold and the Beautiful (with Robert Mitchum's granddaughter Carrie Mitchum, whom he had met on the Big Jake set), 1987 through 1988 which led to a lot of work overseas, and his role as Officer Matt Doyle on The New Adam-12 (Universal Studios) 1989 through 1991.
