"Sunday Morning" is a song written by Tony Kanal, Gwen Stefani, and Eric Stefani for No Doubt's third album Tragic Kingdom (1995). It was released as the album's sixth single in 1997.
Composing the song began when Tony Kanal was having a fight with Gwen Stefani, who was then his girlfriend, through the bathroom door of his parents' house in Yorba Linda, California. Stefani later changed the lyrics to discuss dealing with her breakup with Kanal. .
