Opal were an American alternative/psychedelic band in the 1980s. They were part of the Paisley Underground musical style.

The group formed in the mid-'80s under the name Clay Allison, featuring guitarist David Roback (previously of Rain Parade), bassist Kendra Smith (from Dream Syndicate) and drummer Keith Mitchell. After one single, they released the remaining Clay Allison tracks under the band's new name, Opal, on the 1984 Fell from the Sun EP. Another EP, Northern Line, followed in 1985. These EPs were later compiled and released as Early Recordings
