Haicang (simplified Chinese: 海沧区; traditional Chinese: 海滄區; pinyin: Hǎicāng Qū; Pe̍h-ōe-jī: Hái-chhng-khu) is one of the six county-level districts of Xiamen, People's Republic of China, and one of the four located on the mainland proper, as opposed to on Xiamen Island.

In May 1989, the Chinese government established the Haicang investment zone as a petrochemical industrial area within Xinglin District for Taiwanese business magnate Wang Yongqing.

Since then, Haicang has developed into a world class port, which serves as an industrial and agricultural base for exports.

[2] The Haicang District Investment Zone is located on the lowermost left (or northern) bank of the Jiulongjiang River, to the west of Xiamen Island.

The urban (eastern) area of the District is separated from Xiamen Island by an 870 metres (2,850 ft)-stretch of water crossed by the Haicang Bridge.
