Cychreides (Ancient Greek: Κυχρειδης) is a fabled dragon, or serpent, from Greek mythology. It is named after Cychreus, the Greek demigod who either raised or killed it, depending on the version of the story being told.
Cychreides (alternatively Kykhreides) was one of the pair of serpent dragons that pulled the Greek goddess Demeter's chariot.[citation needed] This chariot was later gifted to the hero Triptolemus to travel the lands spreading grain, resulting in the death of one of the serpents at the hands of King Charnabon of the Getae, however it is unclear if Cychreides is the serpent that was slain at that time
