In Greek mythology, Assaracus was the second son of King Tros 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 Aigesta or Themiste or Clytodora, daughter of Laomedon. Assaracus' son and heir was Capys. He was also a brother of Ganymede.
