Henry Lidgbird Ball (7 December 1756 – 22 October 1818) was a Rear-Admiral in the Royal Navy of the British Empire. While Ball was best known as the commander of the First Fleet's HMS Supply, 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.
