Port of Jeju, Maritime gateway in Jeju City, South Korea

The Port of Jeju is a designated trade port in Geonip-dong, Jeju City, at the island's northern tip. Its passenger terminal has a wide, low facade under a long arched metal roof, with a glass-walled central entrance and palm trees along the front. Blue lettering on the right reads "JEJU COASTAL FER".

The port originated as a natural harbor and was developed into a structured facility in 1913 to handle rising maritime traffic. Its gradual expansion shows how Jeju became increasingly connected to Korean and regional trade routes.

Inside the port area lie Samseonghyeol, three holes from which, according to legend, the three ancestral clans of Jeju — Ko, Pu and Yang — emerged to settle the island. The name Jeju itself was not used until 1221; earlier the island was called Takna, then Tamna-hyeon and Taman-Gun.

The passenger terminal is easy to reach on foot and provides direct connections to buses and taxis for onward travel. Comfortable waiting zones with dining options featuring local food make longer stays manageable.

The port's three Samseonghyeol holes are tied to the legend that Jeju's three founding clans, the Ko, Pu and Yang families, emerged from them to settle the island. The civilian-military complex port opened to the public in 2016 and can berth two 150,000-ton ships.
