Jianghai is a district of Jiangmen City in Guangdong Province, southern China. It is one of the administrative divisions that make up Jiangmen, a prefecture-level city in the Pearl River Delta region of the province.
As a district, Jianghai forms part of the urban and suburban fabric of Jiangmen rather than functioning as an independent city. Its status within the municipal structure means it is governed as part of Jiangmen's broader administration, alongside the city's other districts and county-level divisions.
Jianghai lies in southern China, within Guangdong Province, a coastal province in the country's south. The district's position within Jiangmen places it in the Pearl River Delta, a densely populated and economically significant region of Guangdong.
