The Princes Gate Towers were a set of twin office tower blocks that were located at the intersection of Flinders and Swanston Streets in the Melbourne central business district, Australia. They were designed by architects Leslie M. Perrott and Partners and constructed in 1967. They were partly occupied by the Gas and Fuel Corporation of Victoria, leading to the buildings also being known as 'the Gas & Fuel'. They were demolished in 1997 to make way for Federation Square, the mixed-use development and public space that now occupies the site.
