John Russell Waters (born 8 December 1948, London, England) is a famous film, theatre and television actor, best known in Australia, where he moved to in 1968. He has been in the industry for over 40 years.

His first big break was in musicals, playing Claude in a Sydney production of Hair in 1969, then Judas in Godspell. Among his most famous roles are Sergeant Robert McKellar in the 1976 television series Rush (famously revoiced and parodied by The D-Generation as The Olden Days on their comedy programme The Late Show), Capt. Alfred Taylor in the 1980 film version of Breaker Morant, and Pontius Pilate in the Australian concert production of Jesus Christ Superstar.
