Gigonus or Gigonos (Ancient Greek: Γίγωνος) was an ancient Greek polis (city-state) in the Chalcidice, ancient Macedonia. It is cited by Herodotus as one of the cities—together with Lipaxus, Combreia, Lisaea, Campsa, Smila, Aeneia—located in the vicinity of the Thermaic Gulf, in a region called Crusis near the peninsula of Pallene, where Xerxes recruited troops in his expedition of the year 480 BCE against Greece.[1]
Subsequently the city belonged to the Delian League since it appears on a tribute list to Athens in 434/3 BCE.[2] Gigonus is also cited by Thucydides as the place where the Athenians, under the command of Callias, established a camp in the year 432 BCE when they were heading against Potidaea.[3]
The site of Gigonus is located near modern Nea Kallikrateia.[4][5]
