Insiders were an American rock band from Chicago, Illinois.
The group played locally in the Chicago area in the mid-1980s, and was initially courted by Warner Bros. Records before signing with Epic Records and releasing a debut album in 1987. That album, Ghost on the Beach, peaked at #167 on the Billboard 200 on the strength of a single also titled "Ghost on the Beach", which reached #8 on the Billboard mainstream rock singles chart. The group eventually left Epic and signed with independent label Monsterdisc, releasing two albums for the label in the 1990s.
