KAIKINOS (or Caecinus) was a River-God of the land of Bruttium in southern Italia.

The River Kaikinos flowed down from the Sila Mountains into the Mediterranean Sea between the town of Rhegium and Lokris. The most important neighbouring rivers were the Krataeis of Bruttium, and Symaithos of nearby Sikelia (Sicily).

Pausanias, Description of Greece 6. 6. 4 (trans. Jones) (Greek travelogue C2nd A.D.) :
"Euthymos [who won a boxing contest at the Olympics] was by birth one of the Italian Lokrians . . . Local legend, however, makes him the son . . . of the river Kaikinos (Caecinus) which divides Lokris from the land of Rhegion and produces the marvel of the grasshoppers. For the grasshoppers within Lokris as far as the Kaikinos sing just like others, but across the Kaikinos in the territory of Rhegium they do not utter a sound."
