Augustus Brine (1769 – 28 January 1840) was an officer of the Royal Navy who served during the American War of Independence and the French Revolutionary and Napoleonic Wars. Despite being the son of a prominent naval officer of the American War of Independence, Augustus Brine had a relatively quiet career. He rose through the ranks to his first command during the French Revolutionary Wars, and was serving at the Cape of Good Hope by 1798. In 1799 he was faced with rumours of a mutiny while off Madagascar, and took decisive steps to maintain his authority and suppress any attempted insubordination. In doing so he was able to navigate his ship back to a British port and obtain support from other British ships.
