HMS Blanche was a 1760-ton, 6-gun Eclipse-class wooden screw sloop built for the Royal Navy in the mid-1860s by Chatham Dockyard.

Under the command of Captain Cortland Simpson, she undertook a survey of Rabaul's Harbour in 1872.

While sailing to England she was almost lost rounding Cape Horn in bad weather.

However, it developed a serious leak in the Indian Ocean and was beached on Île Saint-Paul on 19 June 1871.
