Dae Mu-ye, also known as King Mu (Hangul: 무왕; Hanja: 武王) (r. 718–737), was the second king of the Balhae. He is noted for the military expansion of his domain.

Dae Mu-ye was the eldest son of Dae Jo-yeong, the founder of the ancient kingdom of Balhae, He ascended to the throne after the death in 719 of his father. He was given the title of "King of the Gyeru Province" by Tang Emperor Xuanzong. He gave the posthumous title King Go to his father, Dae Jo-yeong. Since then, He declared the era name In-an, an act of independence from China's Tang dynasty. On the other hand, he frequently sent embassies to the Tang, including his sons and brothers.

Balhae's aggressive expansion triggered frictions with Tang China, Silla of southern Korea, the Khitans, the Xi, the Göktürks, and several Mohe tribes. When the Heishui Mohe in the north of Balhae came under the direct control of the Tang in 727, he attacked the Heisui Mohe fearing a pincer attack.

Dae Mun-ye (大門藝), His pro-Tang brother, opposed the military campaign and defected to the Tang. In 732, King Mu ordered a punitive expedition against Tang in present-day Shandong, sending the Balhae navy at the command of Jang Mun-hyu. In the same year, he led troops to Madushan (馬都山) in the vicinity of Shanhaiguan and occupied nearby towns. In 733, Chinese Emperor Xuanzong ordered Dae Mun-ye to attack Balhae, along with forces from Silla, but the attack was unsuccessful and they were repelled.
