Alberto Maranhão Theatre, Opera house in Natal, Brazil.

The Alberto Maranhão Theatre is an opera house in the historic center of Natal, built in the Art Nouveau style with curved lines and ornamental details on its facade. Inside, it has a main auditorium, a stage, and formal reception spaces designed to host a range of live performances.

The theater was built in the late 1800s and opened in 1904 under the name Teatro Carlos Gomes. It was later renamed after Alberto Maranhão, a politician who played a role in shaping cultural life in the region during the early 20th century.

The theater takes its name from Alberto Maranhão, a former governor of Rio Grande do Norte, and today it hosts plays, concerts, and other live events for the people of Natal. Inside, the hall is decorated with plasterwork and gilded details that give it the feel of a classic European opera house.

The theatre stands in the Ribeira neighbourhood, the old riverside quarter of Natal, near the Potengi. Visits depend on the performance calendar, so confirm opening times before setting out. The building is a listed monument, and its 2015–2021 restoration added accessibility and air conditioning.

The theatre is a monument listed by the Institute of Historical and Artistic Heritage of Rio Grande do Norte. Its first director was conductor Joaquim Scipião, and in 2005 the remains of Alberto Maranhão, who died in 1944 and was buried in Paraty, were moved to a memorial inside the theatre.
