Southbank Theatre, Modern theatre in Southbank, Melbourne, Australia.

Southbank Theatre is a contemporary performance venue in Melbourne's Southbank precinct with two distinct spaces. The larger Sumner hall seats 559 people, while the smaller Lawler studio accommodates 150 for experimental works.

The venue opened in 2009 as the principal home of the Melbourne Theatre Company, launching with a production of Poor Boy starring Guy Pearce. The building subsequently received the Victorian Architecture Medal for its design.

The building's exterior displays geometric patterns inspired by American abstract expressionist Al Held. The interior spaces are named after directors John Sumner and Ray Lawler.

Southbank Theatre stands on Southbank Boulevard beside the Melbourne Recital Centre, the two buildings constructed simultaneously. The Sumner seats 559 and the smaller Lawler 150, so check which space your performance is in before arriving. Script Bar & Bistro, function rooms, foyers and two foyer bars serve the venue.

The theatre's two auditoriums are named after director John Sumner and playwright Ray Lawler. The geometric shapes on the facade were inspired by paintings of American abstract expressionist Al Held. The building shares its Southbank Boulevard site with the Melbourne Recital Centre, constructed at the same time.
