HMAS Napier (G97/D13) was an N-class destroyer serving in the Royal Australian Navy (RAN) during World War II.

[1] Napier was the first of the eight-ship N class laid down under the War Emergency Programme when construction started at the Fairfield Shipbuilding and Engineering Company shipyard in Govan, Scotland on 26 July 1939.

[2] Napier was then assigned to Port Said for 2+1⁄2 months, serving as control ship for the harbour's defence at night, while undergoing repairs and refits in the day.

[2] During the remainder of the year, Napier participated in the Tobruk Ferry Service, escorted convoys through the Mediterranean and the Red Sea, and transferred troops between Cyprus and Hafia.

[2] Napier returned to duties with the Eastern Fleet after the unsuccessful convoy run, and in September participated in the Madagascar campaign, particularly the surrender of Majunga and the occupation of Tamatave.

[2] The destroyer commenced patrols of the East Indian Ocean in October, which she continued until March 1943, when she joined the Atlantic anti-submarine force based in South Africa.

[2] Later in the year, the ship sailed to Australia for a long period of refitting at Williamstown, but returned to the Eastern Fleet in early November.

[8] Napier earned six battle honours for her wartime service: "Crete 1941", "Libya 1941", "Indian Ocean 1942–44", "Burma 1944–45", "Pacific 1945", and "Okinawa 1945".
