Gaetano Monti (born Naples, c. 1750 – died there, c. 1816) was an Italian composer.
His name is first recorded in 1758, when he was eight years old, singing in a small part in a performance of Il curioso del suo proprio danno by Niccolò Piccinni.
His first opera, Adriano in Siria, was performed in Modena in 1775, and he was later named organist of the Treasury Chapel at Naples Cathedral; there he remained until 1788.
Most of his works were opere buffe, and were seen in theatres in Rome, Venice, and Naples.
It was believed at one time that he was the brother of the poet Vincenzo Monti, but this is uncertain.
