Ocelis or Okelis was a port on the Red Sea, on the Arabian side near or at Bab al-Mandeb, the strait separating the Red Sea from the Gulf of Aden, part of the ancient reckoning of Arabia Felix. It is placed by Ptolemy a little to the north of the straits of the Red Sea. It belonged to the Elisari, and was subject to Cholebus. The place also sometimes appears as Acila or Akila (Ἀκίλα).
