Kasabian ( kə-SAY-bee-ən) are an English rock band formed in Leicester in 1997 by lead vocalist Tom Meighan, guitarist and second vocalist Sergio Pizzorno, guitarist Chris Karloff and bassist Chris Edwards. Drummer Ian Matthews joined in 2004. Karloff left the band in 2006 and founded a new band called Black Onassis. Jay Mehler joined as touring lead guitarist in 2006, leaving for Liam Gallagher's Beady Eye in 2013, to be replaced by Tim Carter, who later became a full-time band member in 2021. Meighan left the band in July 2020, with Pizzorno stepping up as full-time lead vocalist.

In 2010 and 2014, Kasabian won the Q Awards for Best Act in the World Today. They were named Best Live Act at the 2014 Q Awards and the 2007 and 2018 NME Awards. The band's music is often described as indie rock, but Pizzorno has said he "hates indie bands" and does not feel Kasabian fit into that category.

Kasabian have released eight studio albums – Kasabian (2004), Empire (2006), West Ryder Pauper Lunatic Asylum (2009), Velociraptor! (2011), 48:13 (2014), For Crying Out Loud (2017), The Alchemist's Euphoria (2022) and Happenings (2024). The band's music has been described as a mix of The Stone Roses and Primal Scream with the swagger of Oasis. Their music has won them several awards and recognition in the media, including a Brit Award in 2010 for Best British Group, and their live performances have received praise, the most notable of which was their appearance as headliners at the 2014 Glastonbury Festival.
