Inachus

In Greek mythology, Inachus (Greek: Ιναχος, Inakhos) was the god of the River Inachus in southern Greece. When Poseidon and Hera could not decide who was to be the patron god of Argos, Inachus was chosen to decide and he ruled in Hera's favor. As revenge, Poseidon caused the River Inachus to dry up.

As a river deity, Inachus was one of the Potamoi and, thus, a son of Oceanus and Tethys. Inachus sired several children, including:
 * The Inachides without a consort
 * Io, Phoroneus, Mycene, and Aegialeus by Melia
