William Scott Gorham (born March 17, 1951) is an American guitarist and songwriter who is one of the "twin lead guitarists" for the Irish rock band Thin Lizzy. Although not a founding member of Thin Lizzy, he served a continuous membership after passing an audition in 1974, joining the band at a time when the band's future was in doubt after the departures of original guitarist Eric Bell and his brief replacement Gary Moore. Gorham remained with Thin Lizzy until the band's breakup in 1983.
