Language of Angels is a 2000 play by Naomi Iizuka.
Language of angels may also refer to:
- Angelic tongues, praise of Second Temple Judaism
- Enochian, an occult constructed language recorded in the diaries of John Dee and Edward Kelley, said by them to have been received from angels
- Glossolalia, the "speaking in tongues" of Charismatic Christianity, sometimes interpreted as the speech of angels transmitted through humans
