"Friends" is a single by guitarist Joe Satriani, released in 1992 through Relativity Records. The single contains two instrumental tracks from his Grammy-nominated^[3] fourth studio album The Extremist, with "Friends" reaching No. 12 on the U.S. Billboard Mainstream Rock chart.^[4]

The chord progression of "Friends" generally follows an I–IV–V pattern (with the exception of the bridge sections) in the key of D flat (occasionally D when played live), with heavy use of power chords in the accompaniment. Satriani performs the track using Drop D tuning down a half step and when performing the track live often uses a different guitar. In an interview for Guitar for the Practicing Musician, Satriani stated that he originally composed the song on bass guitar while looking through a book of photographs of smiling children.^{[volume & issue needed]}
