"Pensiero stupendo" (Italian for "Wonderful Thought") is a song written by Ivano Fossati (lyrics) and Oscar Prudente (music), and performed by Patty Pravo.

[1] The song's lyrics are a provocative description of a sexual ménage à trois.

It was originally chosen to launch the French singer Jeanne Mas in the Italian market, but her version did not convince the RCA director Ennio Melis, who thought the song was more appropriate for Pravo.

The B-side of the 7" single was "Bello", a cover of Talking Heads' "Love → Building on Fire".

[4] It was the ninth best-selling single of the year and remains one of the biggest hits of Patty's career.
