Spock's Beard is an American progressive rock band formed in Los Angeles.

The band was formed in 1992 by brothers Neal (lead vocals, keyboards) and Alan Morse (vocals, guitars), John Ballard (bass) and Nick D'Virgilio (drums). Ballard was replaced by Dave Meros before the release of their debut album, The Light (1995), and Ryo Okumoto (keyboards) joined soon after. Neal Morse left the band following the release of their sixth album, Snow (2002), and D'Virgilio took over as the band's frontman. In 2011, D'Virgilio also left and was replaced by Jimmy Keegan (drums) and Ted Leonard (lead vocals) from Brief Nocturnes and Dreamless Sleep (2013) onwards. To date, the band have released thirteen studio albums, and numerous live releases.

The band, particularly the Neal Morse line-up, are considered to be at the forefront of modern progressive rock music. Four of their first six albums featured in the Prog Report's "Top 50 Prog Albums 1990–2015", with The Light and Snow featuring in the top ten.
