Moryllus or Moryllos was a town of ancient Macedonia, earlier assumed to be in the district of Anthemus, but now it is placed, thanks to an inscription, in the interior Mygdonia or Crestonia, near modern Ano Apostoli, Kilkis prefecture. The only attested citizens of Moryllus are two Delphic theorodokoi, Hadymos and Seleukos sons of Argaios (c.230-220 BC).
