Peter Warner (1931 – 13 April 2021) was an Australian seafarer and ship's captain who discovered six Tongan youths marooned on a Pacific island in 1966, more than a year after they had been presumed dead. He later went on to win the line honours three times in the Sydney to Hobart yacht race. He drowned April 13, 2021 when his boat capsized attempting to cross the Ballina Bar at the mouth of the Richmond River.
