The hyperuranion^[1] or topos hyperuranios^[2] (Ancient Greek: ὑπερουράνιον τόπον,^[3][4] accusative of ὑπερουράνιος τόπος, "place beyond heaven"), which is also called Platonic realm, is a place in heaven where all ideas of real things are collected together.^[5] As a perfect realm of Forms,^[3] the hyperuranion is within Plato's view that the idea of a phenomenon is beyond the realm of real phenomena and that everything we experience in our lives is merely a copy of a perfect model.^[6] It is described as higher than the gods since their divinity depended on the knowledge of the hyperuranion beings.^[4]

The hyperuranion doctrine is also a later medieval concept that claims God within the Empyrean exists outside of heaven and controls it as the prime mover from there for heaven even to be a part of the moved.^[1] The French alchemist Jean d'Espagnet rejected the idea of hyperuranion in his work Enchiridion, where he maintained that nature is not divided into conceptual categories but exists in unity.^[7]
