Teatro Comunale Dante Alighieri, Opera house and Italian national heritage in Ravenna, Italy.

The Teatro Comunale Dante Alighieri is an opera house in Ravenna built in the neoclassical style during the 1800s. The main hall contains several tiers of boxes and seating areas that accommodate roughly 830 spectators.

Ravenna's old Teatro Comunitativo, a U-shaped baroque hall with 97 boxes, had become inadequate by the 1830s, so the city commissioned a new theatre from the Venetian brothers Tommaso and Giovan Battista Meduna, who had restored La Fenice. The first stone was laid in 1840 and the house opened on 15 May 1852 with Meyerbeer's Robert le diable, followed by Pacini's Medea. Verdi dominated its first fifty years.

The theatre is named after Dante Alighieri, who was exiled from Florence and spent the last four years of his life in Ravenna. Since 1990 the Alighieri has hosted the Ravenna Festival, whose June and July programmes have brought rare operas by Salieri, Auber and Cherubini to the stage.

The theatre stands at 2 Via Mariani in Ravenna's historic centre, a short walk from the city's main squares. The opera season runs from November to April, with up to six operas, while prose performances are organised by Ravenna Teatro. The Ravenna Festival uses the hall for its June and July programme, so the calendar shifts between seasons.

The neoclassical exterior has four Ionic columns and a portico with statues of four Muses. The auditorium behind it holds 118 boxes on four tiers plus a gallery, in the traditional horseshoe shape, with 830 seats.
