In the ancient Greek myths, ambrosia (, Ancient Greek: ἀμβροσία 'immortality') is the food or drink of the Greek gods, and is often depicted as conferring longevity or immortality upon whoever consumed it.

Ambrosia is very closely related to nectar, the Greek gods' other form of sustenance. The two terms may not have originally been distinguished from each other. For example, in Homer's poems nectar is usually the drink and ambrosia the food of the gods; it was with ambrosia that Hera "cleansed all defilement from her lovely flesh", and with ambrosia that Athena prepared Penelope in her sleep so that when she appeared for the final time before her suitors, the effects of years had been stripped away and the sight of her inflamed them with passion.

A character in Aristophanes' Knights says, "I dreamed the goddess poured ambrosia over your head—out of a ladle." Both descriptions could be correct, as ambrosia could be a liquid considered a food (such as honey).
The consumption of ambrosia was typically reserved for divine beings. Upon his assumption into immortality on Olympus, Heracles is given ambrosia by Athena, while the hero Tydeus is denied the same thing when the goddess discovers him eating human brains. In one version of the myth of Tantalus, part of Tantalus' crime is that after tasting ambrosia himself, he attempts to steal some to give to other mortals. Those who consume ambrosia typically have ichor, not blood, in their veins.
Both nectar and ambrosia are fragrant, and may be used as perfume: in the Odyssey Menelaus and his men are disguised as seals in untanned seal skins, "and the deadly smell of the seal...
