The Protectorate General to Pacify the North or Grand Protectorate General to Pacify the North (647–784) was a Chinese military government established by the Tang dynasty in 647 to pacify the former territory of Xueyantuo, which extended from Lake Baikal to the north, the Gobi Desert to the south, the Khingan Mountains to the east, and the Altay Mountains to the west. It controlled the Mongolian Plateau from 647 to 682.

It was first established as Yanran at Shanyu Tai, southwest of present-day Urat Middle Banner, the northern slope of Lang Shan. This was later shifted to Hanhai a short period before it was changed to Anbei. The seat of governance remained there until the year 687.
