Filippo Galli (1783 – 3 June 1853, in Paris) was an Italian opera singer who began his career as a tenor in 1801 but went on to become one of the most acclaimed basses of the bel canto era, with a voice known for its wide range, extreme agility, and expressivity, and a remarkable gift for acting.^{[according to whom?]}

Born in Rome, Galli was a marginal buffo tenor, appearing in Naples, Bologna, Parma, and Turin, primarily in the works of Nasolini, Generali, and Zingarelli. It is said that following an illness in 1810, his voice changed markedly into that of bass, but this may have been a cover story for his technical transition into the bass repertoire upon the advice of the composer Giovanni Paisiello or singer Luigi Marchesi. Galli's younger brother Vincenzo was also an opera singer noted for his performances in basso buffo roles.

His new career took rise in 1812: his meeting with Rossini allowed him to sing L'inganno felice on 1 August at the Teatro San Moisè, Venice (in the role of Tarabotto). After his creation of Polidoro in Pietro Generali's La vedova stravagante, he appeared in a new opera by Rossini—La pietra del paragone on 26 September 1812. His performance in the "Sigillara" aria was the hit of the immensely successful opera.^{[according to whom?]} His collaboration with Rossini increased: on 22 May 1813 he sang Mustafà in the premiere of L'italiana in Algeri at the Teatro San Benedetto in Venice. Rossini then composed numerous other bass parts specifically for Galli. On 14 August 1814 he appeared in Il turco in Italia at La Scala; on 31 May 1817 (again at La Scala), in the very difficult role of Fernando in La gazza ladra. The title role in Maometto II followed on 3 December 1820 at the Teatro di San Carlo, Naples plus, on 3 February 1823, he sang the role of Assur in Semiramide at La Fenice in Venice.

Galli also created the role of Enrico (Henry) VIII in Donizetti's Anna Bolena at the Teatro Carcano in Milan.
