Teatro Liceo, Theater venue in San Nicolás district, Buenos Aires, Argentina.

Teatro Liceo stands at the corner of Avenida Rivadavia and Paraná, facing Lorea Plaza. The three-story stone building has rusticated walls and tall recessed arched openings on the ground floor, rectangular windows and a balustraded balcony above, and large arched windows with decorative surrounds and a central pediment at the roofline. A curved marquee reading "LICEO" marks the theater entrance.

The building opened in 1872 under the name El Dorado and remains the oldest continuously operating theater building in Buenos Aires. It received National Historical Monument status in 2011.

This venue serves as a gathering place for musical theater lovers who come to watch live performances on stage. The space maintains its role as a cultural hub where local and visiting artists present songs and dances that connect with Buenos Aires audiences.

The building underwent major renovation in 2006 that added modern LED lighting systems while keeping the original fixtures and design. Visitors will find a comfortable theater space that combines traditional features with updated amenities.

In 1993 the owners received an offer to turn the theater into a betting house; Multiteatro S.A., run by Carlos and Tomás Rottemberg, took over and kept it as a theater. The same management carried out a six-month restoration in 2006, with the theater's own workers renewing pipes, ceilings and ventilation and restoring marbles, floors, bronzes and carpets.
