Korea's myths are older than its borders. They begin with a bear who became a woman, a heavenly prince who descended to a sacred mountain, and a kingdom born from a divine bargain. Centuries later, those same stories drive K-drama plot twists, K-pop visuals, and the rites Koreans still observe at temples and shrines. This guide walks through the major figures of Korean mythology, from the founding myth of Dangun to the nine-tailed gumiho, the trickster dokkaebi, the goddesses of Jeju, and the mountain god Sansin.
Dangun: The Founding Myth
The oldest Korean myth, preserved in the 13th-century Samguk Yusa, tells how Hwanung, son of the Heavenly King Hwanin, descended to Mount Taebaek with the wind, rain, and cloud spirits and 3,000 followers. A bear and a tiger asked to become human. Hwanung gave them mugwort and twenty cloves of garlic and told them to stay out of sunlight for one hundred days. The tiger gave up. The bear endured and was transformed into a woman named Ungnyeo. She married Hwanung, and their son, Dangun Wanggeom, founded Gojoseon, the first Korean kingdom, traditionally dated to 2333 BCE.
South Korea still marks October 3 as Gaecheonjeol, or National Foundation Day, in honor of the myth. Dangun also blurs into Sansin, the mountain god of Korean shamanism, who is sometimes painted in the same robes and crown.
Gumiho: The Nine-Tailed Fox
The gumiho, or nine-tailed fox, is the most famous shapeshifter in Korean folklore. Old stories say a fox that survives for a thousand years gains nine tails and the power to take human form, almost always as a beautiful woman. Unlike the more benign Chinese huli jing or the Japanese kitsune, the classical Korean gumiho is dangerous, often feeding on human livers or hearts to maintain her form. Joseon-era tales drew on Chinese accounts of Daji, and Korean writers later adapted them into versions like So-Dal-gi-jeon.
Modern pop culture has softened and rewritten the figure. The 2010 drama "My Girlfriend Is a Gumiho" turned her into a romantic lead. The 2020 tvN series "Tale of the Nine Tailed" cast Lee Dong-wook as a male gumiho hunting demons in present-day Seoul, with a 2023 sequel set during the 1938 colonial period. The character also reaches global gaming through Ahri, the gumiho-inspired champion in League of Legends.
Dokkaebi: Korean Goblins
Dokkaebi are not ghosts. In folklore they are nature spirits born when an inanimate object soaked in human blood or long discarded, like a broom, mortar, or worn tool, takes on its own life. Stories describe them with horns, one leg, glowing red faces, and a magical club called a dokkaebi bangmangi that grants wishes when struck on the ground. They love rice cakes, buckwheat jelly, and wrestling, and they punish the greedy while rewarding the kind.
The 2016 tvN drama "Guardian: The Lonely and Great God," known overseas as "Goblin," recast the dokkaebi as a tragic immortal warrior played by Gong Yoo. It became the first Korean cable drama to cross 20 percent in ratings and turned the dokkaebi into a global icon. Its cast is reuniting in 2026 for a tenth-anniversary travel program on tvN.
Princess Bari and the Roots of Korean Shamanism
Princess Bari, also called Bari-degi or Chil Kongju, is the patron myth of Korean mudang shamans. As told in gut rituals for the dead across most of the peninsula, a king casts out his seventh daughter for being a girl. Years later he and the queen fall mortally ill, and only Bari is willing to travel to the western paradise to retrieve the medicinal Water of Life. She crosses the underworld, marries its keeper, bears him seven sons, and returns to revive her parents. In return she becomes the goddess who guides souls between this world and the next.
The story is still chanted during ssitgim-gut and other funerary rituals, and the National Folk Museum of Korea holds extensive photographic and ritual archives of mudang who recite it. Contemporary choreographers, including Eun-Me Ahn, have built dance works around her journey.
Jeju Island Myths: Jacheongbi and Seolmundae Halmang
Jeju has its own mythological universe, distinct from the mainland and centered on a pantheon of grandmother goddesses, or halmang. The biggest is Seolmundae Halmang, the giantess who created the island. According to the legend, she scooped up dirt in her chima skirt and dropped it into the sea, forming Jeju and its roughly 360 oreum parasitic volcanic cones. The last and tallest peak became Hallasan, today a UNESCO World Heritage site.
Jeju's other great heroine is Jacheongbi, the goddess of grain. Her story, the Segyeong Bon-puri, is a sweeping shamanic epic: she disguises herself as a boy to study alongside the god Mun-doryeong, descends into the underworld to revive a servant, and finally ascends to heaven, where she persuades the celestial bureaucracy to give humans the five grains. Unlike many mainland heroines, she is proactive, witty, and unafraid to bargain with gods.
Cosmic Myths: Sun and Moon Siblings, Chilseong, and Sansin
Korean cosmology is populated by sibling deities and star gods. In "The Sun and the Moon," a folk tale recorded across the peninsula, a brother and sister flee a tiger that has eaten their mother. They climb a rope to the sky, where the gods make the boy the sun and the girl the moon. In some versions she trades places out of shyness, which is why looking directly at the sun is painful.
Chilseong, the Seven Stars, refers to the Big Dipper, which Korean shamanism treats as a cluster of deities who govern lifespan and fortune. Mothers traditionally prayed to Chilseong for healthy children. Sansin, the mountain god, is the most widespread folk deity of all. Almost every Buddhist temple in Korea has a small Sansin shrine, where a white-bearded sage is painted seated under a pine tree beside a tiger. The tiger itself, descended from the failed candidate in the Dangun myth, is the recurring emblem of Korean folklore.
How Korean Myths Live On in K-Drama and K-Pop
Korean mythology never went underground. It just changed costumes. "Goblin" mainstreamed the dokkaebi. "Tale of the Nine Tailed" rebooted the gumiho. Netflix's animated hit "K-pop Demon Hunters" leans on shaman iconography and ritual swords. Webtoons and games, from "Tower of God" to "Mystic Pop-up Bar," mine Princess Bari and the underworld journey for plot. Even idol stage concepts borrow from shamanic and Buddhist visual vocabulary, with mountain spirits, talismans, and ritual fans turning up in K-pop music videos.
The throughline is that Korean myth is still a living tradition. Mudang still perform gut. Families still hang dokkaebi-themed talismans for luck. Hikers still bow at Sansin shrines on the way up Korea's three sacred mountains. The stories that started with Hwanung's descent are still being told, just on bigger screens.

To go deeper, visit the National Folk Museum of Korea at Gyeongbokgung Palace, which has permanent galleries on shamanism, Sansin paintings, and Dangun iconography. The National Museum of Korea holds major Joseon-era sansindo and tiger paintings. On Jeju, the Jeju Folklore and Natural History Museum covers Seolmundae Halmang and Jacheongbi, and the annual Seolmundae Halmang Festival runs every May. For myth-rooted K-drama, start with "Guardian: The Lonely and Great God," "Tale of the Nine Tailed," "Mystic Pop-up Bar," and "Arthdal Chronicles."
