Casey are a Welsh rock band formed in South Wales, United Kingdom in 2014.

The band formed shortly after vocalist Tom Weaver and guitarist Liam Torrance left previous projects, Continents and Hot Damn respectively. Originally formed as a studio band under the name Well Wisher, Weaver and Torrance later recruited Toby Evans, Max Nicolai, and Scott Edwards, and began producing material with the intention of performing live. After a brief hiatus while Weaver auditioned to join the band Northlane, the name Well Wisher was dropped, and the band relaunched under the name Casey. The name is derived from both Weaver's love of the album Casey by The Rise of Science, and also Torrance's tribute to the late <a href="/bands/hawthorneheights">Hawthorne Heights</a> guitarist, Casey Calvert.

Following their tour with Burning Down Alaska and Acres in April 2015, bassist Scott Edwards stepped down from the band, and was replaced by Adam Smith.

On 1 December 2018 the band released a statement explaining that they have decided to disband following a final UK/European tour and a one-off headline show in the US in 2019.

On 1 December 2022, the band announced a return to the music industry with a five date tour of Europe starting in January 2023.
