Caofeidian (Chinese: 曹妃甸; pinyin: Cáofēidiàn) is a land reclamation-converted economic development zone in Bohai Bay located in the eponymous district of Tangshan, Hebei Province, China.

It hosts a large coal and ore discharging port, which forms one of the prime ports of Northern China, namely (from South to North) Tianjin - Jingtang port - Caofeidian - Qinhuangdao - Yingkou - Bayuquan - Dalian). Caofedian and Jingtang ports are often referred together as Tangshan port, though Tangshan is actually a large inland city away from the shore.

The area is served by the Tangshan–Caofeidian railway.

The island is 200 km from Beijing, the island spans 60 km² and is a 2005-listed pilot area for the development of a Recyclable/Circular Economy (Industrial ecology) in China. Huadian Power and PetroChina have some of their energy bases there. The island is expected to have a population of 300,000 by 2010.

Caofeidian is 80 km from Tangshan city centre.
