Kodaline (reads /ˈkoʊdəlaɪn/) are a Dublin-based Irish rock band. Originally known as 21 Demands, the band made chart history in March 2007, when their debut single "Give Me A Minute" topped the Irish Singles Chart; becoming the first independently released track to achieve the feat.

In 2011, the band changed its name to Kodaline. Steve Garrigan and Mark Prendergast grew up in Swords, Dublin and have known each other since childhood. They both attended secondary school at Colaiste Choilm in Swords, where they would take part in many battle of the bands. Years later, they began to share a love for music and at that stage Vinny May, who also lived in Swords, joined the group. The group was not fully complete until January 2012, when their friend, bass player Jason Boland, from Celbridge, Co. Kildare was recruited.
