Tsar is a rock band formed in Los Angeles, California in 1998, with Jeff Whalen on lead vocals and guitar, Daniel Kern on vocals and guitar, Jeff Solomon on bass, and Steve Coulter on drums. They released an eponymous album on Hollywood Records in 2000, which, although a financial disappointment for the label, is considered a hook-laden classic by a growing number of power pop fans.

In 2004 Chuck Byer replaced Coulter and in 2005 Derrick Forget replaced Solomon. In 2005 Tsar released its second full album, Band-Girls-Money, on TVT Records. The album had been recorded nearly two years earlier with Coulter and Solomon.

The 2010 movie 'Super' features the band's debut album title track 'Calling All Destroyers' during the opening credits.
