Ball's Pyramid is an erosional remnant of a shield volcano and caldera that formed about 7 million years ago. It lies 12 mi (20 km) southeast of Lord Howe Island in the Pacific Ocean. It is 1810 ft (552 m) high, while measuring only 3608 ft (1100 m) in length and 984 ft (300 m) across, making it the tallest volcanic stack in the world. Ball's Pyramid is part of the Lord Howe Island Marine Park in Australia.

Ball's Pyramid has a few satellite islets. Observatory Rock and Wheatsheaf Islet lie about 2624 ft (800 m) west-northwest and west-southwest respectively, of the western extremity of Ball's Pyramid. Southeast Rock is a pinnacle located about 2.2 mi (3.5 km) southeast of Ball's Pyramid. Like Lord Howe Island and the Lord Howe seamount chain, Ball's Pyramid is based on the Lord Howe Rise, part of the submerged continent of Zealandia.

The first successful climb to the summit was made on 14 February 1965 by a team of climbers from the Sydney Rock Climbing Club, consisting of Bryden Allen, John Davis, Jack Pettigrew and David Witham.

Climbing was banned in 1982 under amendments to the Lord Howe Island Act, and in 1986, all access to the island was banned by the Lord Howe Island Board. 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.
