Teatro Degollado, Opera house in central plaza of Guadalajara, Mexico.

Teatro Degollado is an opera house in the historic center of Guadalajara, Mexico, distinguished by its neoclassical facade topped with sixteen Corinthian columns. Inside, the main auditorium holds just over a thousand seats arranged in horseshoe tiers, while a smaller chamber hall accommodates around one hundred twenty guests for recitals and readings.

Construction started in 1856 under architect Jacobo Gálvez, following a neoclassical design inspired by European theaters of the nineteenth century. The inaugural performance took place in 1866 with Donizetti's opera Lucia di Lammermoor sung by Mexican soprano Ángela Peralta, marking the building's entry into national cultural prominence.

The theater is home to the Jalisco Philharmonic Orchestra and hosts the Encuentro Internacional del Mariachi y la Charrería, the Ballet Folclórico de la Universidad de Guadalajara and the Ballet del Ayuntamiento. Its stage has seen figures such as Juan Gabriel, Lola Beltrán, Vicente Fernández, Plácido Domingo, Rudolf Nureyev and Marcel Marceau.

Performances take place in the main hall most evenings, while guided tours run during the day and the facade is easily visible from the adjacent plaza. The smaller chamber space upstairs hosts chamber music and talks, drawing a quieter audience than opera nights.

The gilded eagle on the inner arch, placed there between 1877 and 1880 under Fermín Riestra, holds a Mexican flag in its talons and a chain in its beak. The chain is the detail most visitors miss: it hangs from the beak, not the claws, and no source ties it to any local custom.
