World Expo 88, also known as Expo 88, was a specialised Expo held in Brisbane, the state capital of Queensland, Australia, during a six-month period between Saturday, 30 April 1988 and Sunday, 30 October 1988, inclusive. The theme of the Expo was "Leisure in the Age of Technology", and the mascot for the Expo was an Australian platypus named Expo Oz.

The A$625 million fair was the largest event of the 1988 Bicentennial celebrations of the arrival of the First Fleet in Sydney Harbour. Expo 88 attracted more than 15,760,000 visitors who bought tickets worth A$175 million. The event achieved both its economic aims and very good attendances, was successfully used to promote Queensland as a tourist destination and it spurred a major re-development at the South Brisbane site. The core feature of the site were the international pavilions. Many of the exposition's sculptures and buildings were retained by various entities around the state and are still in use or on display today.
