John Peter Farnham (born July 1, 1949) is an English-born Australian pop singer. Domestically he has remained one of Australia's best-known performers over a career spanning more than 30 years. He is the only Australian artist to have a number one record in five consecutive decades (echoing Sir Cliff Richard in the United Kingdom). Between 1982 and 1986 he fronted Little River Band.

Born in Dagenham, East London, United Kingdom, Farnham spent the first years of his life in England before migrating to Australia in 1959.
