Cephissus (Athenian Plain)

Cephissus (Athenian plain) (Greek: Κηφισός; Κηφισσός, Kifissós, Kephissós, Kêphissos) or Cephisus, is a river flowing through the Athenian plain.

The Bibliotheca (3.15.1) declares that Erechtheus' wife Praxithea was daughter of Phrasimus (otherwise unknown to us) by Diogenia (otherwise unknown to us) daughter of Cephissus.

This river is found in the western part of the valley. Today much of the river flows adjacent to the freeway linking Athens and Thessaloniki, and east of mountains of Parnitha and Aegaleo.

• Length: ?km/?mi
• Empties into: Saronic Gulf

In the southern part, the river flows for 15 km under (but originally in the middle of) the highway named Kifissou Avenue.
