Huishan is a town in the Hainan region of China. It is located on Hainan Island, the southernmost province of the country, in the South China Sea.
As a settlement in Hainan, Huishan shares the characteristics of the region, which is known for its tropical climate and coastal setting. The island province is separated from the Chinese mainland by the Qiongzhou Strait.
Detailed information about Huishan specifically is limited; it is a small locality rather than a major urban centre. It should not be confused with the better-known Huishan in Jiangsu Province, which is the site of Huishan National Forest Park in western Wuxi, adjacent to Xihui Park.
