Killer Frost is the name of several characters appearing in American comic books published by DC Comics. All three characters associated with the mantle are metahumans possessing ice powers, and have some connection to the superhero Firestorm.

The first Killer Frost is Crystal Frost, a misandristic scientist who attempts to kill her former professor Martin Stein for rejecting her romantic advances. After Crystal's death, her friend Louise Lincoln takes up the mantle of Killer Frost to seek revenge against Firestorm. The New 52 reboot introduced a new Killer Frost named Caitlin Snow, who eventually reforms and joins the Justice League of America as the superhero Frost.

Various iterations of Killer Frost, primarily Crystal Frost and Louise Lincoln, have appeared in various animated projects and video games, primarily voiced by Jennifer Hale. Additionally, Danielle Panabaker portrayed Caitlin Snow, Killer Frost (later renamed Frost), and Khione in The CW's Arrowverse franchise, such as the television series The Flash.
