Meilichos (Greek: Μείλιχος, Latin: Meilichus[1]) is a torrent in the northwestern part of Achaea, southern Greece.

The river flows from a spring near Skioessa near the northern part of the Panachaiko mountain west of the ravine of Charadros to the Gulf of Patras.

It passes north of Skioessa, under a viaduct of the A5 motorway, through the village Sychaina, now a neighbourhood of Patras, it empties west of the neighbourhood of Agyia.

In antiquity there was a temple of Artemis Triklaria near the river,[2] but this has not yet been found by archaeologists.

Near the intersection of present-day Aretha Street and the Greek National Road 8A in the Patras neighbourhood of Ampelokipoi, a bridge from the Roman era has been excavated.
