Metropolis State Penitentiary

Metropolis State Penitentiary is a maximum security prison featured in media relating to the character of Superman as seen in comic book titles published by DC Comics. The prison is operated by whatever state Metropolis happens to be located in (the establishment of which is an ever-going nebulous mystery).

The worst of the worst of Metropolis' blue collar criminals will find themselves sent upriver to the Metropolis State Pen. The super-powered baddies however are just a little too tough for conventional imprisonment standards, so these guys are actually sent to Stryker's Island Penitentiary, which is more equipped to deal with metahumans.

The Metropolis State Penitentiary was most commonly seen in the realities known as Earth-One and Earth-Two. Like all prisons, they seem to have a revolving door for their inmates, as nobody ever seems to stay in jail for very long. Notable trustees of the good ole Metro State Pen include the likes of Lex Luthor, the Toyman, and the Prankster.
