The Palais Theatre is a former cinema, now functioning exclusively as a concert venue, located in St Kilda, Victoria, Australia. With a capacity of 2,896 people, it is the largest seated theatre in Australia.
The building, which retains many of its original features, is considered one of the finest examples of Art deco architecture in Australia and is on the Victorian Heritage Register. In 2006, the City of Port Phillip, which owns the site, called for tenders by private operators to restore the theatre, as part of the proposed redevelopment of the Triangle Site. However, the redevelopment failed to go ahead and the planned $20 million restoration of the Palais was also abandoned.
