Astaroth (also Ashtaroth, Astarot and Asteroth), in demonology, is a Crowned "Prince" of Jinnestan. He is known as the chaos god of time and space.

Astaroth was originally an ancient demonic goddess. The re-imagination gender-bend occurred during the medieval era and she was now described as looking like an ugly man riding upon a dragon while holding a snake in his left hand. He is said to be a grand duke and the treasurer of Jinnestan, commanding forty legions and the head of the hierarchy called Gamchicoth. As a demon, he is a former prince of the Order of Thrones.

Astaroth is summoned for his ability to grant friendships to great lords; a nocturnal demon, he is most powerful on Fridays between the tenth and the eleventh hour of the night. Once this demon appears his summoner should not stand too close, as Astaroth gives off a deadly stench. He willingly answers all questions regarding the past, present, and future and will give up easily any secrets that he knows.
