In Greek mythology, the Hyperboreans (Ancient Greek: ὑπερβόρε(ι)οι, romanized: hyperbóre(i)oi, pronounced [hyperbóre(ː)oi̯]; Latin: Hyperborei) were a mythical people who lived in the far northern part of the known world. Their name appears to derive from the Greek ὑπέρ Βορέᾱ, "beyond Boreas" (the god of the north wind). Some scholars prefer a derivation from ὑπερφέρω (hyperpherō, "to carry over").
Despite their location in an otherwise frigid part of the world, the Hyperboreans were believed to inhabit a sunny, temperate, and divinely blessed land. In many versions of the story, they lived north of the Riphean Mountains, which shielded them from the effects of the cold north wind. The oldest myths portray them as the favorites of Apollo, and some ancient Greek writers regarded the Hyperboreans as the mythical founders of Apollo's shrines at Delos and Delphi.
