HMAS Parramatta Shipwreck and Memorials is a heritage-listed shipwreck at Cascade Gully, Hawkesbury River, Bar Point, Central Coast, New South Wales, Australia. The heritage listing also includes three related memorials, two at Queens Wharf Reserve in Parramatta and one at Garden Island in Sydney. The original HMAS Parramatta was commissioned in 1910, paid off in 1928, and wrecked in 1934. The bow and stern sections were subsequently converted into memorials, while the third memorial relates to the second HMAS Parramatta, sunk in service at Tobruk in World War II. It was added to the New South Wales State Heritage Register on 15 December 2006.
