Alan Greenwood (born October 20, 1951) is an American rock musician who was a founding member and keyboardist of the rock band Foreigner from 1976 to 1980. He performed on the albums Foreigner (1977), Double Vision (1978) and Head Games (1979). In 2024, Greenwood was selected for induction into the Rock and Roll Hall of Fame, as a member of Foreigner.
In 1981, Greenwood formed the band Spys with former Foreigner bass player Ed Gagliardi, John Blanco, John Digaudio and Billy Milne and recorded the albums Spys (1982) and Behind Enemy Lines (1983).
Greenwood played keyboards on former Rainbow (and future Yngwie Malmsteen's Rising Force and Deep Purple) frontman Joe Lynn Turner's 1985 debut solo album, Rescue You.
Greenwood produced and played keyboards on many Arti Tisi recordings ( with Alice Cooper, Megadeth) and Trans-Siberian Orchestra) guitarist Al Pitrelli.
As per an interview conducted by Dominic Milano from Contemporary Keyboard (Keyboard since 1980), and appeared in the April 1979 issue, Greenwood stated, "When I first got into Foreigner I had a Hammond L-100 and an EML 101 synthesizer, and I think I had an Orchestron, but that's all been changed. Now I use a cutdown Hammond B-3, an ARP Omni, and a Wurlitzer electric piano. I still use the same EML 101, which I've had for about six years, and I just got an Oberheim OB-1, which is a really nice little programmable synthesizer."
