In Greek mythology, Callidice (Ancient Greek Καλλιδίκη) is queen of the Thesprotians in Epirus who receives Odysseus after his propitiatory sacrifices, marries him, and bears Polypoetes. When she dies, Odysseus leaves the kingdom to their son and returns to Ithaca — a Telegony / Apollodorean sequel strand.

I.Queen of Thesprotia
Apollodorus' Epitome has Odysseus, after sacrificing to Hades, Persephone, and Tiresias, journey through Epirus to the Thesprotians. Queen Callidice urges him to stay and offers him the kingdom; they marry and she bears Polypoetes. He defeats neighboring attackers while she shares his rule; at her death he hands the throne to their son and sails home.
The Telegony tradition likewise sends Odysseus on a further voyage after the suitors' slaughter and makes Callidice his Thesprotian wife.
