Qinhuangdao (; postal pinyin: Chinwangtao) is a city in the Hebei province, in China. It is located approx. 300 km east of Beijing, on the Bo Hai (see Bohai Gulf), the innermost gulf of the Yellow Sea.

Since the elevation of Tianjin to a provincial-level municipality, Qinhuangdao is the chief port of Hebei province. The Qin emperor Qin Shi Huang Di is said to have sought immortality on an island in the Haigang district, but did not find it.

• Beidaihe: a seaside resort.
• Haigang District : the harbor city. Qinhuangdao proper. Home of Yan Shan University , the leading university in NE Hebei province.
• Shanhaiguan: a popular tourist destination, featuring the eastern end of the Great Wall.
