Ball's Pyramid is an uninhabited islet in the Pacific Ocean located 20 kilometres (12 mi) southeast of Lord Howe Island, between Australia and New Zealand.

The steep rocky basalt outcrop is the eroded plug of a shield volcano and caldera that formed 6.4 million years ago.

[4] Ball's Pyramid, which is part of Australia's Lord Howe Island Marine Park, is positioned in the centre of a submarine shelf surrounded by rough seas, which makes any approach difficult.

In The Voyage of Governor Phillip to Botany Bay with an Account of the Establishment of the Colonies of Port Jackson and Norfolk Island (1789), Arthur Phillip gives this description of the area around Ball's Pyramid before describing Lord Howe Island: There lies about four miles from the south-west part of the pyramid, a dangerous rock, which shows itself a little above the surface of the water, and appears not to be larger than a boat.

In 1990, the policy was relaxed to allow some climbing under strict conditions, which in recent years has required an application to the relevant state minister.

Observatory Rock and Wheatsheaf Islet lie about 800 metres (2,600 ft) west-northwest and west-southwest respectively, of the western extremity of Ball's Pyramid.

Two pairs were brought to mainland Australia, and new populations have been successfully bred[14] with the ultimate goal of reintroduction to Lord Howe Island.

In 2014, an unauthorised climbing team sighted live stick insects in an exposed position 65 metres (213 ft) below the summit of Ball's Pyramid in a thicket of sedge plants, suggesting that the insect's range on Ball's Pyramid is more widespread than previously held, and that its food preferences are not limited to Melaleuca howeana.
