Campaspe (; Greek: Καμπάσπη, Kampaspē), or Pancaste (; Greek: Παγκάστη, Pankastē; also Pakate), was a supposed mistress of Alexander the Great and a prominent citizen of Larissa in Thessaly. No Campaspe appears in the five major sources for the life of Alexander and the story may be apocryphal. The biographer Robin Lane Fox traces her legend back to the Roman authors Pliny (Natural History), Lucian of Samosata and Aelian's Varia Historia. Aelian surmised that she initiated the young Alexander in love.
