Nasos (Ancient Greek: Νᾶσος) was a town and polis (city-state) of ancient Aeolis. The place-name "Nesos Pordoselene" (Νεσος Πορδοσελήνε) appears in the list of tributes to ancient Athens of the year 422/1 BCE but there are different opinions on whether Nesos (or Nasos) and Pordoselene were a single city or if they are two different cities. On the other hand, the nickname "nasiotas" (Νασιώτας) appears in an inscription of Adramyttium dated to 319-317 BCE.
