In Greek mythology, Assaracus (; , Assarakos) was the second son of Tros, King of Dardania. He inherited the throne when his elder brother Ilus preferred to reign instead over his newly founded city of Ilium (which also became known as Troy). He married Hieromneme, daughter of Simoeis; others say his wife was Clytodora, daughter of Laomedon. Assaracus' son and heir was Capys. He was also a brother of Ganymede.
