In Greek mythology, Calydnus or Kalydnos (Κάλυδνος) was a son of Uranus and the first mythological king of Thebes, after whom the city was thought to have been called Calydna. He was believed to have built the first fortifications of the city, which was why Thebes were sometimes referred to as the "citadel of Calydnus". Calydnus was succeeded by Ogygus.
