Smash Mouth is a pop rock band from San Jose, California.

Formed in 1994, the band comprised Steve Harwell (lead vocals), Greg Camp (guitar), Paul De Lisle (bass), and Kevin Coleman (original drummer). Their hit songs include "Walkin' on the Sun" (1997) and "All Star" (1999).

Focused at times playing third wave ska music, the band has adopted retro styles spanning several decades of popular music, as well as performing covers of popular songs such as The Monkees' "I'm a Believer", War's "Why Can't We Be Friends" and The Beatles' "Getting Better" as well as cult favorites such as the The Four Seasons' "Can't Get Enough of You Baby", which was covered by Question Mark & the Mysterians, (though their version owes more to The Colourfield's interpretation; in fact, the band at first believed it was a Colourfield original). They usually release one cover version per studio album. The band's 1999 release Astro Lounge is their most critically and commercially successful album to date.
