Dropion was an ancient Paeonian king, the son of Leon of Paionia.
Irwin Merker suggests that when Demetrios II and the Aetolian League were at war, "Dropion was involved as an ally of Aitolia." Additionally, he states that "when Demetrios or Antigonos Doson created the Macedonian Koinon he was imitated by his northern neighbor Dropion who hoped in this way both to modernize the constitution of his Kingdom and to increase the support of his subjects."
An inscription, discovered in 1877 at Olympia on the base of a statue, states that it was set up by the community of the Paeonians in honor of their king and founder Dropion.
