Enochian is an occult constructed language — said by its originators to have been received from angels — recorded in the private journals of John Dee and his colleague Edward Kelley in late 16th-century England. Kelley was a scryer who worked with Dee in his magical investigations. The language is integral to the practice of Enochian magic.

A constructed language is a language whose phonology, grammar, and vocabulary, instead of having developed naturally, are consciously devised for some purpose, which may include being devised for a work of fiction. A constructed language may also be referred to as an artificial, planned or invented language, or a fictional language. Planned languages are languages that have been purposefully designed; they are the result of deliberate, controlling intervention and are thus of a form of language planning.
