Gort is a fictional humanoid robot that appeared first in the 1951 American science fiction film The Day the Earth Stood Still and later in its 2008 remake. His depiction varies between film adaptations.

Gort is an 8-foot tall robot constructed from a single piece of "flexible metal". He is but one member of a "race of robots" invented by an interplanetary confederation (described as "a sort of United Nations on a planetary level" by Klaatu, who is a representative of that confederation) to protect their citizens against all aggression by destroying any aggressors. Klaatu describes "him" as one of an interstellar police force, holding irrevocable powers to "preserve the peace" by destroying any aggressor. The fear of provoking these robots acts as a deterrent against aggression.

Gort does not speak, but he can receive and follow verbal commands, including the famous dialog line "Klaatu barada nikto", spoken by actor Patricia Neal's character toward the end of the film.
