Au Revoir Simone is an American indie pop band from Williamsburg, Brooklyn, New York, formed in 2003. The group is composed of Erika Forster (vocals/keyboard), Annie Hart (vocals/keyboard/bass) and Heather D'Angelo (vocals/drum machine/keyboard).

The band's name comes from a line Pee-wee Herman says to a minor character (named Simone) in Tim Burton's 1985 film Pee-wee's Big Adventure. The group's musical inspirations were compared by the band's European label, Moshi Moshi Records, to "a dutifully mined musical thrift store"; these diverse influences include Modest Mouse, Stereolab, the Mountain Goats, Louis Prima, Pavement, the Beach Boys, Björk, Broadcast, Belle & Sebastian, David Bowie, Bee Gees and Billie Holiday.
