Parapotamii or Parapotamioi or Parapotamia (Παραποταμία), both meaning near the river, was a town of ancient Phocis on the left bank of the Cephissus, and near the frontier of Boeotia. Its position is described in a passage of Theopompus, preserved by Strabo, who says that it stood at a distance of 40 stadia from Chaeroneia, in the entrance from Boeotia into Phocis, on a height of moderate elevation, situated between Parnassus and Mount Hedylium; he adds that these two mountains were separated from each other by an interval of 5 stadia, through which the Cephissus flowed. The Cephissus flowed into the territory of Parapotamii after leaving that of Elateia and before that of Panopeus; Parapotamii's territory was adjacent to those of Ambrysus, Panopeus, and Daulis.
