"Hello Muddah, Hello Fadduh! " is a novelty song recorded by Allan Sherman released in 1963. The melody is taken from the ballet Dance of the Hours from the opera La Gioconda by Amilcare Ponchielli, while the lyrics were written by Sherman and Lou Busch.

Allan Sherman was an American musician, satirist and television producer who became known as a song parodist in the early 1960s. His first album, My Son, the Folk Singer (1962), became the fastest-selling record album up to that time. His biggest hit was "Hello Muddah, Hello Fadduh", a comic song in which a boy describes his summer camp experiences to the tune of Ponchielli's Dance of the Hours.
