Hua'an County

 is a county of Zhangzhou City, in the far south of Fujian province, People's Republic of China

The county comprises most of the lower watershed of the Jiulong River's north branch (九龙江北溪) and has long been a transport corridor. The first rail connection to the port of Xiamen, laid during the Great Leap Forward era, came down this valley.

The county seat is Huafeng (华丰镇). East of there, up a tributary valley, is Xiandu town (仙都镇), which features some prime examples of Tulou and Fujian Tulou.
