Monoimus (lived somewhere between 150 - 210 CE) was an Arab gnostic (Arabic name ), who was known only from one account in Theodoret (Haereticarum Fabularum Compendium i. 18) until a lost work of anti-heretical writings (Refutation of All Heresies, book 8, chapter V) by Hippolytus was found. He is known for coining the usage of the word Monad in a Gnostic context. Hippolytus claims that Monoimus was a follower of Tatian, and that his cosmological system was derived from that of the Pythagoreans, which indeed seems probable. But it was also clearly inspired by Christianity, monism and Gnosticis
