Paramore is an American rock band formed in Franklin, Tennessee, in 2004. Since 2017, the band's lineup includes lead vocalist Hayley Williams, lead guitarist Taylor York, and drummer Zac Farro. Williams and Farro are founding members of the group, while York, a high school friend of the original lineup, joined in 2007. Williams is the only member to appear on all six of Paramore's studio albums.

The band was signed to Fueled by Ramen, a subsidiary of Atlantic Records. (Both are owned by Warner Music Group.) Williams was signed to Atlantic separately, as she was scouted when she was a teenager. They were the only label to let her stay in the band instead of going solo, but Atlantic said the rest of the band had to sign to Fueled by Ramen. The group's debut album, All We Know Is Falling (2005), reached number 30 on Billboard's Heatseekers Chart in 2006 and number four on the UK Rock Chart in 2009.

The band's second album, Riot! (2007) became a mainstream success thanks to the success of the singles "Misery Business", "Crushcrushcrush", and "That's What You Get". The album was certified Platinum in the US and the band received a Best New Artist nomination at the 2008 Grammy Awards. Their 2009 follow-up, Brand New Eyes, reached number two on the Billboard 200 and became the band's second-highest-charting album to date. It produced the top-forty single "The Only Exception" and went platinum in Ireland and the UK.

Following the departure of Zac and Josh Farro in 2010, the band released their self-titled fourth album in 2013. Paramore gave the band their first number one song on the US Billboard 200 and was also the number one album in the UK, Ireland, Australia, New Zealand, Brazil, Argentina and Mexico. It included the singles "Still Into You" and "Ain't It Fun", with the latter winning the Grammy Award for Best Rock Song for Williams and York as songwriters, making it Paramore's first Grammy win. The band's lineup changed once again after this album, with bassist Jeremy Davis leaving the band near the end of 2015 and former drummer Zac Farro rejoining the band in 2017. Their fifth and sixth studio albums, After Laughter and This Is Why, were released in May 2017 and February 2023, respectively, to critical acclaim.
