Haimen is a town in Zhejiang Province, China, located on the coast of the East China Sea. It sits at the mouth of the Jiao River and falls within Jiaojiang District, which is the seat of the prefecture-level city of Taizhou. The district takes its name from the Jiao River, and Haimen lies at the point where that river meets the sea.
Its position at the river mouth has historically made it a minor coastal settlement within the Taizhou area, which is known for its fishing industry and maritime trade along the Zhejiang coast. The town is part of the broader Jiaojiang District administrative framework, which serves as the political and economic center of Taizhou.
Further details about Haimen's specific history, economy, or attractions are not well documented in readily available sources, and the town remains largely overshadowed by the larger urban center of Jiaojiang and the wider Taizhou municipality.
