Mr. Freeze, real name Dr. Victor Fries (pronounced as Victor "Frees" or "Freeze"), is a DC Comics supervillain, an enemy of Batman. Created by Bob Kane, he first appeared in Batman #121 (February 1959).

Freeze is a scientist who must wear a cryogenic suit in order to survive, and bases his crimes around a "cold" or "ice" theme, complete with a "cold gun" that freezes its targets solid. In the most common variation of his origin story, he is a former cryogenics expert who suffered an industrial accident while attempting to treat his terminally ill wife, Nora.

In the 1997 film, Batman and Robin, he was portrayed by Arnold Schwarzenegger. Freeze has been portrayed in television series as Batman: The Animated Series and The Batman by actors Michael Ansara and Clancy Brown, respectively.
