Lelang Commandery was a commandery of the Han Dynasty which it established after conquering Wiman Joseon in 108 BC and which lasted until Goguryeo conquered it in 313. Though disputed by North Korean scholars, Western sources generally describe the Lelang Commandery as existing within the Korean peninsula, and extend the rule of the four commanderies as far south as the Han River (Korea), which largely follows along the boundary between modern day North and South Korea. However, South Korean scholars have described its administrative areas as being limited to the Pyongan and Hwanghae regions, whose Southern bounds lie roughly 75 miles North of the Han River.

In 108 BC, Emperor Wu of the Han dynasty conquered the area under King Ugeo, a grandson of King Wiman. The Emperor set up Lelang, Lintun, Xuantu and Zhenfan, known as the Four Commanderies of Han in the northern Korean peninsula and Liaodong peninsula. The Book of Han records Lelang belonged to Youzhou, located in northwestern Gojoseon consisted of 25 prefectures, 62,812 houses, and the population was 406,748. Its capital was located Nakrang-guyok, P'yŏngyang. (Rakrang 樂浪/락랑 is a district in central P'yŏngyang today.)
