Stephen Percy "Steve" Harris (born 12 March 1956) is an English musician, best known as the bassist, band leader, primary songwriter and only constant member of the heavy metal band Iron Maiden (although Dave Murray has played with the group since 1976). In addition, he plays keyboards, and sings backing vocals. He founded the band as a teenager in 1975. He and Dave Murray are the only members of the band to have appeared on all of the band's albums, and as Murray left the band for a few months prior to the first album to join Urchin, Harris is the only member to have remained in the band throughout its duration.
