Amilcare Ponchielli (August 31, 1834 - January 17, 1886) was an Italian composer.

Born in Paderno Fasolaro, now Paderno Ponchielli, Ponchielli studied music at the Milan Conservatoire, writing his first symphony by the time he was ten years old. Two years after leaving the conservatoire he wrote his first opera, I promessi sposi, and it was as an opera composer that he found fame. His best known opera, La Gioconda, was produced in 1876.

He died in Milan and was interred there in the Cimitero Monumentale.

Although Ponchielli was very popular and influential in his lifetime, the only one of his operas regularly performed today is La Gioconda. It contains "The Dance of the Hours", which has become a well known piece in its own right, largely thanks to its use in Walt Disney's 1940 film Fantasia, the 1963 Allan Sherman novelty song, "Hello Muddah, Hello Faddah" and, to a lesser degree, the 1966 Perrey and Kingsley song, "Countdown To 6."
