Pass in the Great Wall of China in Qinhuangdao, Hebei province

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. In 1961, the pass was selected as the Major Historical and Cultural Site Protected at the National Level by the State Council of China, and it was listed as part of the Great Wall as a World Heritage Site by the UNESCO in 1987. The pass is a popular tourist destination at the eastern terminal point of the Ming dynasty Great Wall. The location where the wall meets the Bohai Sea is nicknamed "Old Dragon's Head" (老龙头). The pass lies nearly east of Beijing and is linked via the Jingshen Expressway that runs northeastward to Shenyang. Throughout Chinese history, the pass served as a frontline defensive outpost against ethnic groups from Northeast China (Manchuria), including the Khitan and Jurchen (Manchus). Shanhai Pass is the starting point of the eastern end of the Great Wall, and is the first barrier for guarding the frontier, therefore it is called the "First Pass Under Heaven" (天下第一关).

Located south of Yan Mountain, and north of the Bohai Sea, for centuries the pass guarded the narrow passage between Northeast and Central East China. The Northern Qi dynasty, Sui dynasty and the Tang dynasty constructed passes here. The site was called Yuguan during the Tang dynasty and by 785, a garrison was established there. Eight more garrisons were established from Yuguan to Jinniukou. During the Later Tang and Five Dynasties periods, the territory was controlled by autonomous governors. No garrisons (except Yuguan) remained by the Five Dynasties period. The area and the passes were then controlled by the Liao dynasty. The Liao founded Qianmin County east of Yuguan in present day Shanhaiguan. Garrisons were built in the area under the Jin and Yuan dynasties. In 1381, Ming general Xu Da and his soldiers were ordered to repair the old Yongping (永平) and Jieling (界岭) passes. From this, they constructed the present pass, which was named Shanhaiguan (literally "mountain sea pass") because of its location between the mountains and the sea. In the late 16th century, Ming general Qi Jiguang began fortification and construction of a military city around the pass, building cities and forts to the east, south and north, making it one of the most heavily fortified passes in China. During the Qianlong Emperor's reign under the Qing dynasty, Shanhai Pass became the seat of Linyu County (临榆县城) under the jurisdiction of Yongping Mansion (永平府). In the late Qing dynasty, many forts were built to strengthen coastal defense. During the period of the Republic of China, the pass was under the control of Zhang Zuolin's Fengtian clique, Chiang Kai shek's Nationalist government, the Imperial Japanese Army, and the Jireliao Military Region (冀热辽军区). It was taken over by the Northeast Field Army on November 27, 1948. After the founding of the People's Republic of China, Shanhai Pass was once under the jurisdiction of Liaoxi Province, and later under the jurisdiction of Hebei Province. Shanhai Pass is one of the best preserved passes in the Great Wall.

In 1644, Li Zicheng led a rebel army into the Ming dynasty capital of Beijing, marking the official end of the Ming dynasty. After occupying the capital, Li attempted to enlist the support of Ming general Wu Sangui, commander of the powerful Ningyuan garrison north of the Great Wall. Rather than submit to Li's new Shun dynasty, Wu contacted the Manchu Qing dynasty, suggesting that they combine forces to drive the rebels from the capital. Dorgon, regent of the Qing, marched his army to Shanhai Pass to receive Wu's surrender. Together, Wu and the Manchus defeated Li Zicheng's army near the pass, and Li was forced to abandon the capital. The Qing victory enabled their army to enter Beijing unopposed, and established them as the dominant power in China.

The Shanhai Pass is built as a square, with a perimeter of around The walls reach a height of , and are thick. The east, south and north sides are surrounded by a deep, wide moat with drawbridges over it. In the middle of the pass stands a tall bell tower. All four sides of the Shanhai Pass once possessed a gate or mén (門), with the Zhèndōng Gate (鎮東門) in the east wall, the Yíng'ēn Gate (迎恩門) in the west, the Wàngyáng Gate (望洋門) in the south and the Wēiyuǎn Gate (威遠門) in the north. Due to lack of repairs over the centuries, only the Zhèndōng Gate remains today. This was the most important gate due to its position, which faces outside the pass towards Beijing.

Shanhaiguan railway station on Beijing Harbin railway and Tianjian Shanhaiguan railway is the nearest railway station to reach Shanhai Pass.
