Dolphins have long played a role in human culture.
Dolphins are sometimes used as symbols, for instance in heraldry.

In Greek myths, dolphins were seen invariably as helpers of humankind.
Dolphins also seem to have been important to the Minoans, judging by artistic evidence from the ruined palace at Knossos.
During the 2009 excavations of a major Mycenaean city at Iklaina, a striking fragment of a wall-paintings came to light, depicting a ship with three human figures and dolphins.
Dolphins are common in Greek mythology, and many coins from ancient Greece have been found which feature a man, a boy or a deity riding on the back of a dolphin.
The Ancient Greeks welcomed dolphins; spotting dolphins riding in a ship's wake was considered a good omen.
In both ancient and later art, Cupid is often shown riding a dolphin.
A dolphin rescued the poet Arion from drowning and carried him safe to land, at Cape Matapan, a promontory forming the southernmost point of the Peloponnesus.
There was a temple to Poseidon and a statue of Arion riding the dolphin.

The Greeks reimagined the Phoenician god Melqart as Melikertês (Melicertes) and made him the son of Athamas and Ino.
He drowned but was transfigured as the marine deity Palaemon, while his mother became Leucothea. (
cf Ino.)
At Corinth, he was so closely connected with the cult of Poseidon that the Isthmian Games, originally instituted in Poseidon's honor, came to be looked upon as the funeral games of Melicertes.
Phalanthus was another legendary character brought safely to shore (in Italy) on the back of a dolphin, according to Pausanias.

Dionysus was once captured by Etruscan pirates who mistook him for a wealthy prince they could ransom.
After the ship set sail Dionysus invoked his divine powers, causing vines to overgrow the ship where the mast and sails had been.
He turned the oars into serpents, so terrifying the sailors that they jumped overboard, but Dionysus took pity on them and transformed them into dolphins so that they would spend their lives providing help for those in need.
Dolphins were also the messengers of Poseidon and sometimes did errands for him as well.
Dolphins were sacred to both Aphrodite and Apollo.

When heraldry developed in the Middle Ages, not much was known about the biology of the dolphin and it was often depicted as a sort of fish.
Traditionally, the stylised dolphins in heraldry still may take after this notion, sometimes showing the dolphin skin covered with fish scales.

Dolphins are present in the coat of arms of Anguilla and the coat of arms of Romania, and the coat of arms of Barbados has a dolphin supporter.

A well-known historical example of a dolphin in heraldry, was the arms for the former province of the Dauphiné in southern France, from which were derived the arms and the title of the Dauphin of France, the heir to the former throne of France (the title literally means "The Dolphin of France").

"Dolfin" was the name of an aristocratic family in the maritime Republic of Venice, whose most prominent member was the 13th Century Doge Giovanni Dolfin.

In Hindu mythology the Ganges river dolphin is associated with Ganga, the deity of the Ganges river.
The dolphin is said to be among the creatures which heralded the goddess' descent from the heavens and her mount, the Makara, is sometimes depicted as a dolphin.

The Boto, a species of river dolphin that resides in the Amazon River, are believed to be shapeshifters, or encantados, who are capable of having children with human women.

There are comparatively few surviving myths of dolphins in Polynesian cultures, in spite of their maritime traditions and relevance of other marine animals such as sharks and seabirds; unlike these, they are more often perceived as food than as totemic symbols.
Dolphins are most clearly represented in Rapa Nui Rongorongo, and in the traditions of the Caroline Islands they are depicted similarly to the Boto, being sexually active shapeshifters.
