Marino Faliero (or Marin Faliero) is a tragedia lirica, or tragic opera, in three acts by Gaetano Donizetti. Giovanni Emanuele Bidéra wrote the Italian libretto, with revisions by Agostino Ruffini, after Casimir Delavigne's play. It is inspired by Lord Byron's drama Marino Faliero (1820) and based on the life of Marino Faliero (c.1285-1355), the Venetian Doge.
It premiered on March 12, 1835 at the Théâtre-Italien, Paris, and its Italian premiere the following year at the Teatro Alfieri, Florence.
Rossini commissioned a new opera from each of Donizetti and Bellini for production at the Théâtre-Italien (where he was the music director from 1824-1826). Bellini created I puritani to great popular success and Donizetti, Marino Faliero, his first Paris premiere.
The action takes place in Venice in 1355.
