"Sunday Morning" is a song by American band No Doubt for their third studio album, Tragic Kingdom (1995). It was written by Gwen Stefani, Eric Stefani, and Tony Kanal, produced by Matthew Wilder, and released as the record's fifth single on May 27, 1997. The song has also been included on their 2003 greatest hits album, The Singles 1992–2003. Its lyrics describe a romantic relationship that ended in a breakup and was inspired by a discussion that Gwen Stefani had with Kanal. The song has been described as a ska and ska punk recording with elements of reggae and Motown (music style).
"Sunday Morning" received largely positive reviews from music critics who frequently deemed it a standout track on Tragic Kingdom. It has since been included on critics' lists of best No Doubt and Stefani-penned songs. The song was not released as a commercial single in the United States, making it ineligible to enter the Billboard Hot 100 chart. However, it managed to peak at number 35 on the Mainstream Top 40 component chart. It also reached number two in Iceland and the top 40 in Australia and Canada. Elsewhere, the song obtained lower positions.
The song's music video, directed by Sophie Muller, was the fifth and final video made for Tragic Kingdom. It features the band playing "Sunday Morning" in a garage to a lonesome man who strolled past their house. No Doubt later prepares a large dinner for themselves and once they settle in their backyard to eat, they engage in a food fight. The band has performed the single during many of their live appearances, including at their 1995–97 Tragic Kingdom World Tour and while serving as the guest musical act on The Tonight Show with Jay Leno in April 1997. Stefani, individually, performed the track at her 2018–2020 concert residency in Las Vegas.
