No Doubt is an American rock band from Anaheim, California, formed in 1986. For most of its career, the band has consisted of vocalist and founding member Gwen Stefani, guitarist Tom Dumont, bassist Tony Kanal and drummer Adrian Young. Keyboardist Eric Stefani, Gwen's brother, was also a former member when the band started to release albums in 1992. Since the mid-1990s, trombonist Gabrial McNair and trumpeter Stephen Bradley have performed with the band as session and touring musicians.

Though its 1992 eponymous debut album failed to make an impact, its ska punk-inspired follow-up The Beacon Street Collection sold over 100,000 copies in 1995, more than triple the sales of its predecessor. The band's diamond-certified album Tragic Kingdom (1995) benefited from the resurgence of third-wave ska in the 1990s, and "Don't Speak", the third single from the album, set a record when it spent 16 weeks at the number one spot on the Billboard Hot 100 Airplay chart. "Just a Girl", co-written by Stefani, was described as "the most popular cut on the CD".

The band's next album, Return of Saturn (2000), did not match the success of their previous album, despite its Top 40 hit single "Simple Kind of Life". However, the album received critical praise and was nominated for Best Rock Album at the 43rd Grammy Awards. The following year, the band returned with the album Rock Steady (2001), which incorporated reggae and dancehall music. The album was primarily recorded in Jamaica and featured collaborations with Jamaican artists Bounty Killer, Sly and Robbie and Lady Saw. The album produced two Grammy-winning singles, "Hey Baby" and "Underneath It All"; "Hella Good" was also nominated for a Grammy award.

After a 2004 tour, the band members pursued solo projects, with Stefani releasing two successful solo albums Love. Angel. Music. Baby. (2004) and The Sweet Escape (2006), while Tom Dumont released his own solo music project, Invincible Overlord. In 2008, the band resumed working slowly on their sixth and latest effort, titled Push and Shove (2012), and released its lead single "Settle Down". The band has sold over 33 million records worldwide.
