Pandion (/ˈpændiən/ or /ˈpændiɒn/; Ancient Greek: Πανδίων) was the eponymous hero of the Attic tribe Pandionis, which was created as part of the tribal reforms of Cleisthenes at the end of the sixth century BC.[1] He is usually assumed to be one of the two legendary kings of Athens, Pandion I or Pandion II.
