Okjeo () was an ancient Korean tribal state which arose in the northern Korean peninsula from perhaps the 2nd century BCE to the 5th century CE.
Dong-okjeo (Eastern Okjeo) occupied roughly the area of the Hamgyŏng provinces of North Korea, and Buk-okjeo (Northern Okjeo) occupied the Duman River region.
Dong-okjeo was often simply called Okjeo, while Buk-okjeo was also sometimes referred to as Chiguru (置溝婁, 치구루) or Guru (구루), the latter name being also applied to Goguryeo. Okjeo bordered the other minor state of Dongye on the south, and shared a similar fate.
History

In its early history, Okjeo oscillated between domination by the Chinese commanderies and by Goguryeo. From the 3rd century BCE to 108 BCE, it was controlled by Gojoseon. At 107 BCE, it became part of the Xuantu Commandery. As the Xuantu Commandery retreated towards the liadong peninsula as a result of expansion of Goguryeo, East okjeo became part of the eastern part of the Lelang Commandery. However, Christopher I. Beckwith considers Okjeo to have been a dialect of Goguryeo.
