Taicang is a county-level city under the jurisdiction of Suzhou, Jiangsu province, China.

The city located in the south of the Yangtze River estuary opposite Nantong, being bordered by Shanghai proper to the south, while the river also delineates much of its northeastern boundary along Chongming Island.

Under the Ming, Taicang's Liuhe Harbor was the departure point for Zheng He's treasure fleets.

It was also during this period that the shoals in the Yangtze estuary which later became Chongming Island were placed under the supervision of Taicang Prefecture.

The city has the German Centre for Industry and Trade Taicang (Chinese: 太仓德国中心).
