Point Nepean marks the southern point of The Rip and the most westerly point of the Mornington Peninsula, in Victoria, Australia. It was named in 1802 after the British politician and colonial administrator Sir Evan Nepean by John Murray in HMS Lady Nelson. Its coast and adjacent waters are included in the Port Phillip Heads Marine National Park, while its land area is part of the Point Nepean National Park. The point includes Cheviot Beach on its southern side, notable as the site of the disappearance in 1967 of Australia's then-Prime Minister Harold Holt.
