Frou Frou () are a British electronic duo composed of musician Imogen Heap and producer/songwriter Guy Sigsworth. They released their only album, Details, in 2002. The duo wrote, produced, and played instruments on the tracks, while Heap also provided lead vocals. In 2004, they recorded a cover of "Holding Out for a Hero" by Bonnie Tyler, which was used in the credits of the 2004 film Shrek 2. Frou Frou amicably disbanded later that year.

In 2017, Heap and Sigsworth reunited as Frou Frou for Heap's Mycelia Tour. They released an EP of unreleased Frou Frou demos for Details' 20th anniversary in 2022.
