Three ships of the Royal Australian Navy have borne the name Swan, for the Swan River in Western Australia, a continuation of the Avon River, which flows through Perth and into the Indian Ocean at Fremantle.

The first HMAS Swan (D-61) was a River class destroyer laid down by the Cockatoo Docks and Engineering Company Propriety Limited at Sydney in New South Wales on 22 January 1913, launched on 11 December 1915 by Lady Creswell, wife of Sir William Creswell, the First Naval Member of the Commonwealth Naval Board and commissioned on 16 August 1916. HMAS Swan paid off for disposal at Sydney on 15 May 1928 and was broken up for scrap at Cockatoo Dockyard in 1930.

The second HMAS Swan was a Grimsby class sloop.

The third HMAS Swan (50) was a River class destroyer escort laid down by the Williamstown Dockyard at Melbourne in Victoria on 16 February 1965, launched on 16 December 1967 and commissioned on 20 January 1970. HMAS Swan paid off on 13 September 1996 and was scuttled as a dive wreck off Dunsborough in Western Australia on 14 December 1997.
