"Prisencolinensinainciusol" is a song composed by Adriano Celentano, and performed by Celentano and his wife, singer/actress-turned-record producer Claudia Mori. A very popular performance of the song, broadcasted by RAI, shows Celentano with showgirl Raffaella Carrà, who is dancing and lyp-synching to Mori's vocals. It was first released as a single on November 3, 1972, and later on his album Nostalrock. The lyrics are pure gibberish, often described as sounding like American English as heard by a non–English-speaker.

In an interview, Celentano explains that the song is about "incommunicability" because in modern times people are not able to communicate to each other anymore. He added the only word we need is prisencolinensinainciusol, which is supposed to stand for "universal love."

Celentano's rationale for the song was that, after releasing albums about ecology and social issues, "having just recorded an album of songs that meant something, I wanted to do something that meant nothing".

The song was recorded at least twice for television broadcast.
