HMS Hyacinth was an 18-gun Royal Navy ship sloop. She was launched in 1829 and surveyed the north-eastern coast of Australia under Francis Price Blackwood during the mid-1830s. She took part in the First Opium War, destroying, with HMS Volage, 29 Chinese junks. She became a coal hulk at Portland in 1860 and was broken up in 1871.

Francis Price Blackwood was a British naval officer who while posted at several different locations during his time in the Royal Navy, spent much of his time posted in colonial Australia and was an instrumental pioneer of regions near Australia's east coast and nearby islands.
