California Jam II (also known as Cal Jam II) was a music festival held in Ontario, California, at the Ontario Motor Speedway on March 18, 1978, and produced by Leonard Stogel, Sandy Feldman, and Don Branker.

[1] CBS Records concurrently released a two-LP soundtrack album of selections from the concert, the track listing of which appears below.

Selections from Bob Welch and Foreigner were not included in the soundtrack, as only artists who were contracted to one of CBS's labels were represented.

Local radio stations KMET & KLOS aired live simulcasts of the show.

Many in attendance listened to the concert on the radio, due to the poor quality of the sound system.
