Juqu Mujian (; before 420 – 447), named Juqu Maoqian (沮渠茂虔) in some sources, formally Prince Ai of Hexi (河西哀王), was a king of the Xiongnu-led Northern Liang dynasty of China—with most Chinese historians considering him the last king, although with some considering his brothers Juqu Wuhui and Juqu Anzhou who ruled from Gaochang to be kings of the state as well. By the time that Juqu Mujian succeeded his father Juqu Mengxun (Prince Wuxuan) in 433, Northern Liang appeared to be stronger than ever, yet was under the shadow of the much stronger state Northern Wei, to which Northern Liang was nominally a vassal. In 439, Emperor Taiwu of Northern Wei launched a major campaign against Northern Liang and captured both his capital Guzang (姑臧, in modern Wuwei, Gansu) and Juqu Mujian himself. Juqu Mujian remained an honored Northern Wei subject as Emperor Taiwu's brother-in-law until 447, when Emperor Taiwu, believing him to be trying to rebel, forced him to commit suicide.
