Greek Theatre, Open-air theatre in Baton Rouge, United States.

The Greek Theatre is an open-air theater in Baton Rouge designed to present musical performances and concerts within a structure inspired by traditional Greek architecture. The venue accommodates thousands of spectators in tiered seating that rises gradually from a central stage.

Built into a hill as a natural amphitheater, the Greek Theatre opened in 1925 with seating for about 3,500, enough for the entire university population. It hosted convocations, rallies, pageants and commencement exercises. In the early 1930s the area behind it was cleared and landscaped as the Sunken Gardens, with a 150-foot reflecting pool and an 8-foot statue of Hernando de Soto.

The theatre is managed by the University Union and still serves for outdoor concerts, performances and religious ceremonies. In summers 2001 and 2002 the Pass the Hat Festival staged free Shakespeare productions there, including Macbeth and Julius Caesar. In autumn 2020 the Tiger Marching Band rehearsed in the theatre full time during the pandemic.

The theatre is set into a natural hillside on the LSU campus, with tiered seating facing a central stage; the open area behind it, once the Sunken Gardens, is now a tree-shaded lawn. It is managed by the University Union and remains an outdoor venue, so check the weather before events and expect no roofed shelter. Access is on foot across campus, and the grounds are used for concerts, ceremonies and student gatherings.

The theatre was dug into a hillside as a natural amphitheater. Behind it, the Sunken Gardens opened in the early 1930s with a reflecting pool 150 ft long, 30 ft wide and 2 ft deep, ending at an 8 ft statue of Hernando de Soto. The pool was later filled in and the statue thrown into the Mississippi River.
