Rear-Admiral of the Blue Henry Lidgbird Ball (7 December 1756 – 22 October 1818) was a Royal Navy officer who served in the French Revolutionary and Napoleonic Wars. While Ball was best known as the commander of the First Fleet's HMAT Supply (1759), he was also notable for the exploration and the establishment of colonies around what is now Australia and New Zealand. Specifically, Ball explored the area around Port Jackson and Broken Bay, helped establish the Norfolk Island penal settlement, and discovered and named Lord Howe Island.
Ball joined the Royal Navy and was a crewman of various ships, before being commissioned as a lieutenant on 23 April 1778. Ball's first command was HMS Seaflower off the Northern Irish coast from 1783 until 1786. In October 1787 Ball was appointed to command HMAT Supply and to join Captain Arthur Phillip's expedition to establish a penal colony in New South Wales. The expedition departed England on 13 May 1787, and Supply was accompanied by 10 other ships. Of all the ships in the fleet, Supply reached Botany Bay first, on 18 January 1788. Supply would remain in the colony under the overall command of Governor Phillip, and transport persons to establish a secondary settlement on Norfolk Island after which Supply was mainly used to transport supplies and people between the two settlements.
