Phrontis (Ancient Greek: Φροντίς) is the son of Onetor and helmsman of Menelaus. Homer says Apollo slew him with gentle shafts at Cape Sunium as he held the steering-oar of the homeward ship; Menelaus stopped to bury his comrade before sailing on. He is distinct from Phrontis son of Phrixus among the Colchian nephews and from Phrontis wife of Panthous at Troy.

I.Helmsman of Menelaus
In the Odyssey, Nestor tells Telemachus that Phoebus Apollo assailed with his gentle shafts and slew the helmsman of Menelaus as he held the steering-oar of the speeding ship — Phrontis son of Onetor, who excelled the tribes of men in piloting when the storm winds blow strong.
Menelaus, though eager for his journey, tarried at Sunium in Attica to bury his comrade and pay funeral rites before sailing on. The cape burial anchors Phrontis in the Returns rather than in the war at Troy.
II.Homonyms
This atlas entry (phrontis-sparta) is Menelaus' pilot. Apollodorus and Apollonius name a different Phrontis among the sons Phrixus begot on Chalciope in Colchis — Argus, Melas, Phrontis, and Cytisorus. Homer's Iliad also mentions queenly Phrontis, wife of Panthous and mother of Euphorbus, Hyperenor, and Polydamas — a Trojan woman who shares the name only.
