Saenger Theatre, Theatre building on Canal Street, New Orleans, United States.

The Saenger Theatre is a brick movie palace on a downtown Canal Street corner, its base clad in white stone and topped by a vertical blade sign spelling "SAENGER" in bulbs. Architect Emile Weil designed the interior as an atmospheric theatre recalling an Italian Baroque courtyard, with 150 ceiling lights set in the shapes of night-sky constellations. Machines projected moving clouds and sunrises across the auditorium.

The Saenger Theatre opened on February 4, 1927, after three years of construction at a cost of $2.5 million, as the flagship of Julian and Abe Saenger's theatre empire. In 1929 Julian Saenger sold it to Paramount Publix for $10 million, and in 1933 it switched to talking pictures only. In 1964 ABC Interstate Theatres walled off the balcony to create a second, upstairs house called the Saenger Orleans. It was named a New Orleans landmark in September 1977 and added to the National Register of Historic Places that December.

The theatre's name comes from the Saenger brothers, Julian and Abe, whose movie-palace chain had this building as its flagship. Its ceiling holds 150 lights arranged as night-sky constellations, and machines once projected moving clouds and sunrises across the auditorium. In 1980 Johnny Carson performed at the grand reopening.

The Saenger stands at the corner of Canal and North Rampart Streets in downtown New Orleans, outside the French Quarter. The main entrances are recessed off Canal Street, and the adjacent 1101 Canal Street building holds the box office and restrooms. The theatre is on the National Register of Historic Places.

Architect Emile Weil set 150 lights into the auditorium ceiling in the pattern of night-sky constellations, and machines projected moving clouds and sunrises across the interior. The 2010s restoration replaced that ceiling with LED lights while keeping the constellation layout.
