The Teatro Contavalli was an opera house and theatre located at Via Mentana #2, in Bologna, region of Emilia-Romagna, Italy.
Long since utilized as a theater, the site is now occupied by offices for the Centro Italiano di Documentazione sulla Cooperazione e L' Economia Sociale.
The theater was inaugurated on 3 October 1814, under the patronage of doctor and entrepreneur, Antonio Contavalli, in a lot that once formed part of the Carmelite convent affiliated with the church of San Martino.
In 1876, a new production company, the Accademia Filodrammatica Albergati was formed under marchese Gioacchino Napoleone Pepoli, and affiliated with this theater.
In 1888 Alfredo Testoni, with the help of the Società del Dottor Balanzone, who was affiliated with the Contavalli, formed a company dedicated to performances in local dialect and vernacular.
