"So Yesterday" is a song by American singer Hilary Duff for her second studio album, Metamorphosis (2003). It was written and produced by The Matrix (a production team consisting of Lauren Christy, Scott Spock and Graham Edwards), with additional writing from Charlie Midnight. The song is influenced by pop rock music, and the lyrics chronicle the protagonist getting over a breakup with her boyfriend, declaring him as "so yesterday". The song received mixed to positive reviews from music critics, with some of them noting its close similarity to Avril Lavigne's works, while others named it one of Duff's best songs.

"So Yesterday" premiered on AOL Music's "First Listen" on June 27, 2003. It was serviced to mainstream radio in the United States on July 14, 2003. The song became Duff's first single to chart in the US Billboard Hot 100 where it reached number 42. It was more successful outside the US, reaching the top 40 in most countries it charted, peaking at number two in Canada, number eight in Australia and France, and number nine in the United Kingdom; in Australia the song was certified platinum.

The song was accompanied by a music video, directed by Chris Applebaum, which showed Duff playing a prank on her ex-boyfriend. It was successful on various music video channels like MTV and MuchMusic. Duff performed the song on her Metamorphosis Tour and has since performed it on all her concert tours. The song is also featured on the compilations Most Wanted (2005), 4Ever Hilary (2006) and Best of Hilary Duff (2008), and the music video game Band Hero.
