Roger Fisher (born February 14, 1950) is an American guitarist primarily known as one of the founding members of the band Heart.

The band Heart started out as Army in 1967 in Seattle, Washington, formed by bassist Steve Fossen and brothers Roger and Michael Fisher.

Following the release of the Dog and Butterfly album, the Roger Fisher / Nancy Wilson romance came to an end.

In 1990, Roger Fisher formed the band Alias with vocalist Freddy Curci and guitarist Steve DeMarchi, who were previously members of the Canadian rock band Sheriff; the other two musicians were fellow ex-Heart members Steve Fossen on bass and Mike Derosier on drums.

He has recorded two solo albums and has collaborated with many musicians in the Pacific Northwest USA, including session/touring percussionist Matthew Burgess.
