Dae Joyeong (대조영; 大祚榮; [tae.dʑo.jʌŋ] or [tae] [tɕo.jʌŋ]; died 719), also known as King Go (고왕; 高王; [ko.waŋ]), established the state of Balhae, reigning from 699 to 719.

Dae Jo-yeong was the first son of general Dae Jung-sang of Goguryeo, where he was born in Goguryeo.

After the fall of Goguryeo to the Silla-Tang armies, Dae Jung-sang remained in a part of Goguryeo which had not been attacked during the 3rd Goguryeo-Tang war. Afterward, Dae Jung-sang was opposed to the Tang. In the confusion of the Khitan uprising led by Li Jinzhong against the Tang (Zhou) in May 696, Dae Jung-sang led at least 8,000 Goguryeo remnant peoples, the Sumo Mohe people, to Dongmo mountain, and the Baishan Mohe leader Geolsa Biu made an alliance and sought independence.

The Tang killed Geolsa Biu, and Dae Jung-sang also died. Dae Jo-yeong integrated the armies of Goguryeo people and some Malgal tribes and resisted Tang's attack. His overwhelming victory over the Tang at Tianmenling enabled him to expand his father's empire. He claimed himself the King of Jin in 698. He established his capital at Dongmo Mountain in the south of today's Jilin province, and built Dongmo mountain fortress, which was to become Jin's capital.
