Inakhos (Ιναχος) was a river god of Argolis in the Peloponnesos, southern Greece. The Inakhos River flowed south through western Argos, emptying into the Argolic Gulf between the towns of Argos and Tiryns. Its stream ran dry in mid-summer. Three other Argive streams personified were the stream Erasinos. There were two additional small tributaries the Asterion, Kephisos as well as three neighboring rivers, Ladon in Arkadia to the west of Inakhos, Asopos in Sikyonia north of Inakhos to the north and Eurotas in Lakedaimonia south-west of Inakhos.

When the gods Poseidon and Hera contested for dominion over Argos, Inakhos was appointed arbiter and decided in Hera's favour. In retalation Poseidon dried up his stream.
