The Chuja Islands (Korean: 추자군도; Hanja: 楸子群島) are a group of 42[1] islands in the Jeju Strait, about halfway between Jejudo and the southern coast of Jeollanamdo.

Only four islands are inhabited: Sangchuja ("Upper Chuja"), which is connected by a bridge to Hachuja ("Lower Chuja"), the largest by area; Hoenggan; and Chupo.

[2][3] As of December 31, 2019, the population is 1,733, based on the number of citizen registrations.

Chuja Islands are administered by Jeju City, but are geographically located adjacent to Wando-gun, Jeolla North Province, and the language and culture is similar to that of Jeolla North Province.

Sinyang Fishing Port is a national fishing harbor located at Sinyang-1-ri, and is known for having a vast, arch-type, minimalist coast, and not the concrete that is common at other Korean ports.
