I'm afraid you just missed my lieutenant Delphin, God of the Dolphins.

Poseidon to Percy Jackson, in The Last Olympian

Delphin (also known as Delphinus) is the Greek god of Dolphins. He works in the service of Poseidon as one of his lieutenants.


Delphin was born to Pontos and Thalassa. After Poseidon became the ruler of the sea, Delphin became one of his lieutenants. When Amphitrite fled from his master's courtship, Delphin went in search of her and persuaded her to agree to the marriage. For this service, Poseidon placed him amongst the stars as the constellation Delphinus.

The Last Olympian

Delphin was briefly seen during Poseidon's battle with Oceanus, the Titan of the Sea. Poseidon tells him to give orders to Palaemon and his Shark Legions.


And there was a dolphin - just a regular dolphin, but it was staring at the map intently.

–Delphin's appearance, in The Last Olympian

In The Last Olympian, Delphin was described as looking just like a regular dolphin. However, due to his status as a god, it is assumed that he can his appearance as he desired.


It is presumed that Delphin has the standard powers of a god.

  • Aquatic Authority: As the God of Dolphins, Delphin can speak to and control dolphins.
  • Persuasion: Delphin was shown to have remarkable skills of persuasion. He managed to convince Amphitrite to marry Poseidon by cleverly yet realistically highlighting all the benefits she could enjoy if she did.



  • The word Dolphin comes from his name.
  • The Delphinidae family of Cetaceans is named after him.
  • In myths, he is thought to be the first dolphin.
