Glenn Lewis Frey (born November 6, 1948 in Detroit, Michigan) is an American musician, singer, songwriter, and actor, best known as one of the founding members of rock band Eagles.

After a stint in 1971 backing Linda Ronstadt, Frey helped form the Eagles, playing guitar and keyboards. Frey wrote or co-wrote (often with Don Henley) many of the group's songs, and sang lead vocal on a number of Eagles hits including "Take It Easy," "Already Gone," "Tequila Sunrise," "Lyin' Eyes," "New Kid in Town" and "Heartache Tonight."

The Eagles broke up in 1980 and reunited in 1994, when they released an album mixing both live tracks and four new songs, Hell Freezes Over.

2007 saw the release of the Eagles' album Long Road Out of Eden.
