Erichthonius of Dardania in the context of Batea (daughter of Teucer)

In Greek mythology, Tros (/ˈtrɒs/; Ancient Greek: Τρώς, Ancient Greek: [trɔ́ːs]) was the founder of the kingdom of Troy, of which the city of Ilios, founded by his son Ilus took the same name, and the son of Erichthonius by Astyoche (daughter of the river god Simoeis) or of Ilus I, from whom he inherited the throne. Tros was the father of three sons: Ilus, Assaracus and Ganymede and two daughters, Cleopatra and Cleomestra. He is the eponym of Troy, also named Ilion for his son Ilus. Tros's wife was said to be Callirrhoe, daughter of the river god Scamander, or Acallaris, daughter of Eumedes.

Another Tros was a Trojan warrior. According to Homer's Iliad, he is the son of the Lycian Alastor and he was slain by Achilles.

The name Astyoche (/əˈstaɪəkiː/; Ancient Greek: Ἀστυόχη means 'possessor of the city') or Astyocheia /ˌæstioʊˈkiːə/ Ancient Greek: Ἀστυόχεια was attributed to the following individuals in Greek mythology:

• Astyoche, naiad daughter of the river god Simoeis, mother of Tros by Erichthonius.
• Astyoche, a Trojan princess as the daughter of King Laomedon by Strymo, Placia or Leucippe, sister of Priam, wife of Telephus and mother of Eurypylus (some call her daughter of Priam and wife of Eurypylus). She was bribed by Priam with a gold vine to persuade Eurypylus to go to the Trojan War, which resulted in him being killed in the battle (cf. the story of Eriphyle). Together with Aethilla and Medesicaste, she was taken captive after the sack of Troy and set fire to the Greek ships during their stay on the Italian coast.
• Astyoche, a Minyan princess as the daughter of King Actor of Orchomenus, son of Azeus. She was the mother of Ascalaphus and Ialmenus with Ares. The latter lay with her in secret when the maiden entered into her upper chamber.
• Astyoche, sister of Agamemnon and Menelaus. She married Strophius, and became the mother of Pylades. She is also known as Anaxibia or Cydragora.
• Astyoche, a daughter of King Phylas of Ephyra, mother of Tlepolemus by Heracles. Also known as Astydameia or Astygeneia.
• Astyoche, wife of Phylacus, mother of Protesilaus and Podarces. These two are otherwise known as grandsons of Phylacus through Iphiclus.
• Astyoche, one of the Niobids.
• Astyoche, mother of Pentheus, otherwise known as Agave.
• Astyoche, daughter of Itylus and possible mother of Ajax the Lesser.
• Astyoche, mother of Euryalus by Mecisteus.
