The Princess Theatre, originally Princess's Theatre, is a 1452-seat theatre in Melbourne, Victoria, Australia. Established in 1854 and rebuilt in 1886 to a design by noted Melbourne architect William Pitt, it is the oldest surviving entertainment site on mainland Australia. Built in an elaborate Second Empire style, it reflects the opulence of the "Marvellous Melbourne" boom period, and had a number of innovative features, including state of the art electric stage lighting and the world's first sliding ceiling, which was rolled back on warm nights to give the effect of an open-air theatre.

Henry Eli White, also known as Harry White, was a New Zealand-born architect best known for the many theatres and cinemas he designed in New Zealand and Australia in the 1910s and 1920s. Many of the major surviving historic venues in the two countries are White designs, including the St. James Theatre, Wellington, St. James Theatre, Auckland, the Capitol Theatre and State Theatre in Sydney, and the Palais Theatre and the interiors of the Princess Theatre and Athenaeum Theatre in Melbourne. He also designed the City Hall and the attached Civic Theatre in Newcastle, New South Wales.
