Stacy's Mom

"Stacy's Mom" is a song by American rock band Fountains of Wayne. It is the third track on their third studio album, Welcome Interstate Managers, and was released to radio as the album's first single on May 19, 2003, through S-Curve Records and Virgin Records. "Stacy's Mom" was written by bassist Adam Schlesinger and vocalist Chris Collingwood, both of whom produced the song alongside Mike Denneen. Its subject matter was inspired by a friend of Schlesinger's when he was young who was attracted to Schlesinger's grandmother. It is a power pop song with which the group hoped to emulate the sound of American rock band the Cars.

"Stacy's Mom" reached number 21 on the US Billboard Hot 100, becoming the band's highest-charting hit in the United States. Additionally, the song peaked within the top 10 in Ireland and the top 20 in the United Kingdom, Australia, and Canada. The single was certified gold by the Recording Industry Association of America for sales of over 500,000 copies, and it was nominated for a Grammy Award for Best Pop Performance by a Duo or Group With Vocals at the 46th Annual Grammy Awards. The song was accompanied with a music video in which model Rachel Hunter plays the title role. "Stacy's Mom" was the only mainstream hit by Fountains of Wayne.

Authorship of "Stacy's Mom" is credited to Chris Collingwood and Adam Schlesinger; in practice, the two songwriters wrote independently, and agreed to credit both writers on all Fountains of Wayne songs regardless of the actual author. In interviews, Schlesinger took responsibility for the song.
