In Greek mythology, Themiste (Ancient Greek: Θεμίστη) was a Trojan princess and daughter of King Ilus of Troad and possibly, Eurydice or Leucippe. She was the (half) sister of Laomedon, Tithonius and Telecleia. Themiste was married off by Ilus to her cousin Capys, son of Assaracus and Hieromneme. With him she became the mother of Anchises and possibly, Acoetes. The former son would later become the father of the famous Aeneas while the later one, became the father of the priest Laocoon.
