The Teatro Donizetti is an opera house in Bergamo, Italy.
The official opening of the house, under the name the Teatro Riccardi, did not occur until 24 August 1791 with a production of Pietro Metastasio's Didone abbandonata set to music by multiple composers, including Ferdinando Bertoni, Giacomo Rampini, Johann Gottlieb Naumann, Giuseppe Gazzaniga, and Giovanni Paisiello.
In 1797 the original theatre was destroyed by a fire, possibly by arson.
Lucchini was contracted again to design a new structure to replace the old one and the new house opened on 30 June 1800.
Donizetti was born in Bergamo's Borgo Canale quarter and his first opera, Il Pigmalione (composed 1816), was given its world premiere at the theatre on 13 October 1960.
