Huangchuan County (simplified Chinese: 潢川县; traditional Chinese: 潢川縣; pinyin: Huángchuān Xiàn; local pronunciation: Huāngchuǎn Xiàn) is a county of southeastern Henan province, People's Republic of China.

[3] According to the ancient Chinese text Bamboo Annals, Huangchuan was the national capital of the first Kingdom of Huang in the Xia dynasty during the 21st century BCE.

Remains of the capital of the Kingdom of Huang were discovered in Longgu, a township six kilometers northwest to the urban area of Huangchuan.

And now residents in Huangchuan are mainly descendants of migrants from Jiangxi, Fujian and Guangdong settled down during the Kangxi era in the Qing dynasty.

Local residents usually call it Little Huang River (pinyin: Xiǎo Huáng Hé).
