In Greek mythology, Callithoe or Kallithoe () was an Eleusinian princess as the eldest daughter of King Celeus and Metaneira. Her name derives from the Greek roots kallos (beauty) and theo (to run), sometimes interpreted as "beautiful runner".
Together with her sisters Demo, Callidice and Cleisidice, Callithoe encountered the goddess Demeter at the virgin well Callichoros in Eleusis, who was resting there in the disguise of an old woman (Doso) in search of her daughter Persephone, who was stolen by Hades, and invited her to her father's house.
