Mother Boxes are fictional devices in Jack Kirby's Fourth World setting in the DC Universe.

Created by Apokoliptian scientist Himon using the mysterious Element X, they are generally thought to be sentient, miniaturized, portable supercomputers, although their true nature and origins are unknown.

In a 2008 article, John Hodgman observed: "Mister Miracle, a warrior of Apokolips who flees to Earth to become a 'super escape artist', keeps a 'Mother Box' up his sleeve — a small, living computer that can enable its user to do almost anything, so long as it is sufficiently loved.

In Kirby's world, all machines are totems: weapons and strange vehicles fuse technology and magic, and the Mother Box in particular uncannily anticipates the gadget fetishism that infects our lives today.
