Shanhai Pass or Shanhaiguan is one of the major passes in the Great Wall of China, being the easternmost stronghold along the Ming Great Wall that commands the narrowest choke point in the strategic Liaoxi Corridor, a crucial coastal landway between the North and Northeast China. It is located in Shanhaiguan District, Qinhuangdao, Hebei province, on the east bank of the Shi River between the Yan Mountains and the Liaodong Bay coast.

The Great Wall of China is a series of fortifications that were built across the historical northern borders of ancient Chinese states and Imperial China as protection against various nomadic groups from the Eurasian Steppe. Several walls were built from as early as the 7th century BC, with selective stretches later joined by Qin Shi Huang (220–206 BC), the first emperor of China. Little of the Qin wall remains. Later on, many successive dynasties built and maintained multiple stretches of border walls. The best-known sections of the wall were built by the Ming dynasty (1368–1644).
