Teatro Broadway, Performance venue near Obelisk in Buenos Aires, Argentina

Teatro Broadway is an Art Deco theatre at 1155 Avenida Corrientes in downtown Buenos Aires, Argentina, designed by Hungarian architect Jorge Kálnay and opened in 1930. Its single original hall had a paraboloid roof and a 12-metre overhang above the stalls, with no columns, thanks to 18-metre Vierendel beams. The upper eight floors, once rental housing, now hold a hotel.

Designed by Hungarian architect Jorge Kálnay for the film entrepreneur Augusto Álvarez, the Broadway was built by the German firm Wayss and Freytag and inaugurated on 11 October 1930 with the premiere of The Underwater Tragedy (20th Century Fox). Until 1939 it hosted premieres from MGM, Paramount, Columbia and 20th Century Fox. In 1954 the sound system was modernized for CinemaScope, and the single hall was later divided in two.

Avenida Corrientes, where the theater stands, is often called the Argentine theater street, comparable to Broadway in New York. On evenings, the sidewalks fill with people choosing between shows at the different venues along the avenue.

The theatre sits on one of the busiest stretches of Avenida Corrientes and is easy to reach on foot from several metro stations. Shows typically start in the evening, so arriving early gives you time to walk around the neighborhood beforehand.

The theatre's single hall was split into two screens, and in 1999 the upper eight floors, originally rental housing with a small confectionery, became the Broadway Hotel & Suites. In 2010 a hall was named after actress Moria Casán; earlier tributes to Narciso Ibáñez Menta and Raúl Rossi were removed around 2004.
