Teatro Llave, Theatre building in Orizaba, Mexico.

Teatro Llave is a neoclassical Italian-style theatre in Orizaba, designed by architect Joaquín Huerta. It seats 436 spectators and has a metal roof installed in 1865, the first of its kind in Mexico.

General Ignacio de la Llave, born in Orizaba in 1818 and governor of Veracruz in 1861–62, promoted the theatre in 1855; architect Joaquín Huerta designed it. It opened in 1875 with a performance by contralto María Jurieff, after de la Llave's death in 1863. In the 1960s it operated as a cinema, and a 1973 earthquake nearly destroyed it; restoration took twelve years and it reopened in 1985.

This theatre serves as a gathering place for local artists and visitors interested in traditional and contemporary performances throughout the year. The spaces host a range of artistic events that shape the cultural life of the city.

The theatre is accessed through its main entrance in downtown Orizaba and reached via typical stairs at street level. It is wise to arrive early on event days, as performances often fill up and nearby parking can be limited.

The theatre's original wooden roof was replaced in 1865 by a metal cover, the first of its kind used in Mexico. The building was designed by architect Joaquín Huerta and seats 436 spectators.
