HMAS Yarra, named for the Yarra River, was a River-class torpedo-boat destroyer of the Royal Australian Navy (RAN). Ordered in 1909 for the Commonwealth Naval Forces (the predecessor of the RAN), Yarra was temporarily commissioned into the Royal Navy on completion in 1910 and handed over to Australian control on arrival in Australia.
From 1914 to 1917, Yarra was involved in wartime patrols in the Pacific and South East Asian regions, before she and her sister ships were transferred to the Mediterranean for anti-submarine operations. She returned to Australia in 1919 and was used primarily to train naval reservists. Decommissioned into reserve then reactivated on five occasions between 1919 and 1928, Yarra was paid off for the final time in 1928, was taken to Cockatoo Island Dockyard for stripping, then was sunk in 1932 as a target ship.
Yarra was one of the first seven ships to form the Royal Austalian Navy.
