101 Collins Street is a 260 m (850 ft) skyscraper located in Collins Street, Melbourne central business district, Victoria, Australia. The 57-storey building designed by Denton Corker Marshall was completed in March 1991. Towards the end of project, with a change of developer, the foyer space was designed by John Burgee, noted as a pioneer of postmodern architecture.^[1]

It overtook Rialto Towers and became the tallest building in Melbourne and Australia until August 1991, when 120 Collins Street was completed. As of 2022, the tower is the sixth-tallest building in Melbourne and the 11th-tallest building in Australia when measured up to the tallest architectural point, which is the 60 m (200 ft)-tall spire.^[2]

The tower contains 83,000 m² (890,000 sq ft) of rentable space. The floor-to-ceiling height is unusually large for a skyscraper at 2.77 m (9 ft 1 in). The 30 m (98 ft) lifts can reach speeds of 7 m/s (23 ft/s). There are 414 underground car park spaces. The building contains double glazed windows with surface coated tempered glass to increase thermal efficiency.

A large part of the site for 101 was created by demolishing the 26 floor CRA Building, the tallest in the city in the mid 1960s.^[3] It the first skyscraper to be demolished in the city.^[4]

The owners of 101 Collins have implemented a strategy of buying adjacent properties to safeguard the building's views, particularly towards the south. As a result, Flinders Lane has experienced an emergence of new restaurants and bars in older buildings.^[5]

101 Collins Street lends its name to a Yarra Trams stop that is served by routes 11, 12, 48 and 109.^[6]
