Chicago 17 is the fourteenth studio album by American band Chicago, released on May 14, 1984. It was the group's second release for Full Moon/Warner Bros. Records and their last with founding bassist/vocalist Peter Cetera.
A total of four singles were released from the album, all of which placed in the top 20 on the Billboard Hot 100 chart.
In 2006, Rhino Entertainment remastered and reissued the album, using the original analog versions of "Please Hold On" (which was co-written with Lionel Richie who was enjoying success from his album Can't Slow Down) and "Prima Donna" and adding a Robert Lamm demo, "Where We Begin" as a bonus track.
