The Gallikos (Greek: Γαλλικός) is a river in Central Macedonia, Greece.

It was known as the Echedoros (Εχέδωρος) in antiquity and the Gomaropnichtis (Γομαροπνίχτης) in the Middle Ages.

The current name probably derives from the ancient Roman colony of Callicum (modern Kilkis) near the river.

It rises in the Krousia Mountain and flows into the Aegean Sea in the Thermaic Gulf, near Sindos.
