Sherwood is an indie rock band from San Luis Obispo, California, specializing in upbeat pop rock. The band began in late 2002 while several of its founding members were attending Cal Poly in San Luis Obispo, California. The band first formed with Nate Henry on vocals and bass, Dan Koch on drums, and Chris Armstrong on guitar. The name Sherwood comes from an inside band joke about creating a concept album that synced with the 1973 Disney Robin Hood cartoon in the same way that Pink Floyd's The Dark Side Of The Moon is said to sync with The Wizard of Oz. In April 2003, the lineup was changed with the addition of drummer Joe Greenetz. Koch became the band's second guitarist and principal songwriter.

After years of touring with a "do-it-yourself" attitude, the band chose to sign with Militia Group side-label Sidecho Records, who would release their debut LP. Entitled Sing, But Keep Going and produced at Sonikwire Studios in Irvine, California by Michael Rosas (singer/guitarist for the band Satisfaction), it sold over 20,000 copies and helped stir up even more attention for the group.

As Sing, But Keep Going continued to gain traction, the band began receiving interest from other labels as they went on to play the Vans Warped Tour and sold-out shows across the country. After holding out for the best possible deal, the band surprised its fans and announced that they had signed to the newly formed Myspace Records. Following another summer stint on the Warped Tour, Sherwood spent six weeks in a beach house near Ensenada, Mexico writing for their next LP. The songs written during this time, along with the material they'd released on the Summer EP, were compiled to form a new full-length album, later entitled A Different Light, which was recorded in December 2006 at Motor Studios in San Francisco with producer Lou Giordano and features his daughter Joanna as a violinist in "I'm Asking Her To Stay."

A Different Light was released in March 2007, in the middle of the band's nationwide tour supporting Relient K and Mae. Sherwood spent the rest of the year supporting several other bands they had met on the Warped Tour including Motion City Soundtrack and The Academy Is..., and ended 2007's unrelenting schedule with a tour in England alongside Hellogoodbye and Say Anything.

Sherwood spent 2008 continuing their support of A Different Light with two more European tours, a trip to Japan, and several headlining U.S. tours. In August, the band moved to Oakland, California to begin writing material for their third full-length album, QU, which would be produced by Brad Wood in Los Angeles. Sherwood released QU in October 2009.

The band formally broke up in 2012 after ten years together. However, in 2015, the band announced that they would be starting an Indiegogo account in order to crowdfund their fourth album. The band's projection to raise $20,000 was reached in just five days and just under $40,000 in total was raised by the time the campaign ended.
