HMS Penguin was an Osprey-class sloop. Launched on 1876, Penguin was operated by the Royal Navy from 1877 to 1881, then from 1886 to 1889. After being converted to a survey vessel, Penguin was recommissioned in 1890, and operated until 1908, when she was demasted and transferred to the Australian Commonwealth Naval Forces for use as a depot and training ship in Sydney Harbour. After this force became the Royal Australian Navy, the sloop was commissioned as HMAS Penguin in 1913. Penguin remained in naval service until 1924, when she was sold off and converted into a floating crane. The vessel survived until 1960, when she was broken up and burnt.
