Yellowcard is an American rock band who formed in Jacksonville, Florida, in 1997. Their official lineup currently consists of lead singer and rhythm guitarist Ryan Key, who was previously a guest vocalist, lead guitarist Ryan Mendez, bassist Josh Portman and violinist Sean Mackin. Mackin is the only remaining original member. Primarily a pop-punk group, their music is recognized for having a distinct and unique sound in its genre due to their prominent use of a violin. The group's most-recognized singles include "Ocean Avenue", "Only One", and "Lights and Sounds". Released in 2003, "Ocean Avenue" and its parent album of the same name are both certified double platinum and platinum in the US respectively by the Recording Industry Association of America (RIAA); "Only One" and the band's 2006 album Lights and Sounds have been certified gold.

During their first two decades together, the band released ten studio albums, with the last, Yellowcard, released in 2016. Following this release and supporting tour, the quartet disbanded. The band announced a reunion in May 2022 and resumed their recording and touring career, beginning with the Childhood Eyes EP, released in 2023. Their eleventh studio album Better Days followed in 2025.
