Enochian is a name often applied to an occult or angelic language recorded in the private journals of John Dee and his seer Edward Kelley in the late 16th century. The men claimed that it was revealed to them by angels. Some contemporary scholars of magick consider it a constructed language that is nonetheless viable for magickal workings, while other scholars of constructed languages simply consider it a very poor imitation of an ancient language, with grammar derived primarily from English.

The angelical language as revealed to Dee and Kelley encompasses a limited text corpus. Additionally, only parts of it come with English translations. Nonetheless, some linguists, notably Donald Laycock, have studied Enochian, arguing against any extraordinary features in the language.

Dee's journals did not describe the language as "Enochian", instead preferring descriptors like "Angelical", the "Celestial Speech", the "Language of Angels", the "First Language of God-Christ", the "Holy Language", or "Adamical" because, according to Dee's Angels, it was used by Adam in Paradise to name all things. The term "Enochian" comes from Dee's assertion that the Biblical Patriarch Enoch had been the last human (before Dee and Kelley) to know the language.
