Huachi County (simplified Chinese: 华池县; traditional Chinese: 華池縣; pinyin: Huáchí Xiàn) is a county in the east of Gansu province, China, bordering Shaanxi province to the north and northeast.

Huachi has a low population density and is one of the poorer counties of China, partly because of the dry climate.

During the Five Dynasties period it was abolished, becoming part of neighbouring counties.

During the first encirclement campaign against the Shaanxi–Gansu Soviet it was home to the Nanliang communist base.

[1] Huachi's important agricultural produce includes white melon seeds, daylily, wood ear mushroom and millets.
