Chuck Panozzo (born Charles Salvatore Panozzo in Chicago) is a bass player. A longtime member of the rock band Styx, he founded the group with his fraternal twin brother, drummer John Panozzo, who died in July 1996. After three decades as a Styx mainstay, Chuck Panozzo left the band shortly thereafter, though he has reappeared with the band occasionally.

In 2001, Panozzo announced he was gay and living with HIV, having been diagnosed in 1991. A serious illness in 1998 gave him the determination to get well, return to performing and come out as a gay man with HIV. Since his coming out he has been involved in campaigning for AIDS awareness and gay rights. He has also survived prostate cancer.
