Rangrang-guyŏk or Rangrang District is one of the 18 kuyŏk that constitute the city of Pyongyang, North Korea.

The Lelang Commandery was, according to the Book of Han, composed of 27 districts and had a population of over 406,748 people.

Located on the Taedong River at the approximate location of modern Pyongyang, archeological evidence suggests that the seat of the commandery had been moved to this district here after the destruction of Wanggeom-seong, the old Koguryo capital at Pyongyang and is claimed to have been original seat of the lelang commandery.

Japanese archaeologists Torrii Ryuzo and Imanishi Ryu, in particular, were instrumental in the tomb excavations and in identifying the Nakrang Earthen Castle in Tosong-ri as the seat of the commandery.

[3] However, North Korea claims that all tombs are in fact of the Koguryo period, as it denies the existence of the Chinese settlement of Lelang, claiming it was a Koguryo city-state, and that the thousands of Chinese artifacts merely represent the burgeoning trade that the State of Nakrang had with the Han.
