The Cosmic Cube is a fictional object appearing in American comic books published by Marvel Comics. There are multiple Cubes in the Marvel Universe, all of which are depicted as containment devices that can empower whoever wields them. Although the first version, introduced in Tales of Suspense #79 (July 1966) and created by Stan Lee and Jack Kirby, originated on Earth as a weapon built by Advanced Idea Mechanics, most are of alien origins.
The Cube (renamed the Tesseract) plays a central role in several films of the Marvel Cinematic Universe, in which it is ultimately depicted as containing the Space Stone, one of the six Infinity Stones.
