Cosi Fan Tutti Frutti is a 1985 album by the British New Wave group Squeeze. It is the band's sixth album, and the first recorded since their breakup in 1982. It reunited songwriters Glenn Tilbrook and Chris Difford with drummer Gilson Lavis and keyboardist Jools Holland (now credited as "Julian"). Keith Wilkinson, who played bass on the 1984 Difford & Tilbrook album, joined Squeeze for the first time. He would stay with the band for over a decade, making him the longest-lasting bassist in Squeeze's history. Laurie Latham produced the album, giving it a distinctly '80s feel that stands apart from the sound of Squeeze's other records.

The album's title is a play on the name of the Mozart opera Cosi fan tutte, roughly translated as "They [women] are all like that." The album's cover art expands this into a visual pun, with a picture of a tea cozy (cosi), a fan, and a tutti-frutti dessert.

In 1997, the CD was released in the UK with two bonus tracks, as part of the Six of One... box set. The set included the band's first six studio albums, each digitally remastered. These CDs were made available for individual purchase in 1998.
