In Greek mythology, Eurotas (Greek: Εὐρώτας) was a son of Myles and grandson of Lelex, eponymous ancestor of the Leleges, the pre-Greek people residing, in the myth, in the Eurotas Valley. He had no male heir, but he did have a daughter, Sparta. Eurotas bequeathed the kingdom to her husband, Lacedaemon, the son of Taygete, after whom Mount Taygetus is named, and Zeus, according to Pausanias. Lacedaemon renamed the state after his wife. "The city is called Sparta to this day."

Pausanias says "It was Eurotas who channelled away the marsh-water from the plains by cutting through to the sea, and when the land was drained he called the river which was left running there the Eurotas." The "cutting through" is seen by Pausanias' translator and commentator, Peter Levy, S.J., as an explanation of Eurotas (or Vrodamas) Canyon, a ravine north of Skala where the river has cut through the foothills of Taygetus after changing direction to the west of the valley.

The Bibliotheca gives a slight variant of the mythological generation of Eurotas: the latter is the son of Lelex, born from the ground (autochthonos) and Cleocharia, a Naiad (water-nymph).
