Pucheng County (simplified Chinese: 浦城县; traditional Chinese: 浦城縣; pinyin: Pǔchéng Xiàn) is a county under the jurisdiction of the municipality of Nanping, in northern Fujian province, People's Republic of China, bordering Jiangxi to the northwest and Zhejiang to the east; it is the northernmost county-level division of Fujian.

Pucheng comprises 3,383.02 square kilometres (1,306.19 sq mi) in the Wuyi Mountains which separates Fujian and Jiangxi provinces.

It borders Songxi County to the southeast, Jianyang District to the south and Wuyishan City (location of the famous UNESCO park) to the west, all within Nanping.

The municipality of Shangrao, Jiangxi, borders to the northwest; those of Quzhou, to the north, and Lishui, to the east, are in Zhejiang.

It is however not demonstrably a member of the Min subgroup (which covers almost all of Fujian), and pending further research must stand as an isolate - the sole exemplar of the Pucheng group of Southern Chinese.
