Spock's Beard is a progressive rock band formed in 1992 in Los Angeles by brothers Neal and Alan Morse. Neal (keyboards/vocals) and Alan (guitars) were joined by fellow musicians Nick D'Virgilio (NDV, drums) and Dave Meros (bass), and were later joined by veteran keyboardist Ryo Okumoto.

Spock's Beard play a brand of progressive rock with pop music leanings, drawing much influence from Genesis and The Beatles. They are also well known for their intricate multi-part vocal harmonies and use of counterpoint much in the vein of Gentle Giant. They've released records like the acclaimed The Kindness of Strangers and V before releasing the epic concept album Snow, which also marked the departure of leader and main composer Neal Morse for a solo career as a Christian artist.

After the departure of Neal Morse, the frontman role was taken on by Nick D'Virgilio. The 'new' lineup has released three more studio albums: Feel Euphoria, Octane and Spock's Beard.

The band was named for the Star Trek episode "Mirror, Mirror" where the crew enters a parallel universe in which the parallel Mr. Spock is differentiated by his beard.
