Mosman is a suburb on the Lower North Shore of Sydney, in the state of New South Wales, Australia. Mosman is located 8 kilometres north-east of the Sydney central business district and is the administrative centre for the local government area of the Municipality of Mosman.
In February 1997, a notice was published in the Government Gazette by Mosman Council advising that they had assigned Mosman as the only suburb in the Mosman Local Government Area. However, Mosman Council decided that residents should continue to be allowed to use the following traditional locality names if they wished:
Mosman is named after Archibald Mosman (1799–1863) and his twin brother George, who moved onto a 4-acre (16,000 m2) land grant in the area in 1831. They were involved in shipping, and founded a whaling station on a bay in the harbour, which became known as Mosman’s Bay. George subsequently became involved in grazing, but Archibald continued with whaling activities. By 1838, he owned 108 acres (0.44 km2) along the Mosman waterfront. Archibald was buried in the cemetery of St Jude's Church, Randwick. His grave is maintained by Mosman Council.
