Zhangjiajie National Forest Park is a national forest park located in Zhangjiajie, Hunan Province, China. It is one of several national parks within the Wulingyuan Scenic Area. In 2004, Zhangjiajie geopark was listed as a UNESCO global geopark.

The most notable geographic features of the park are the pillar-like formations that are seen throughout the park. Although resembling karst terrain, this area is not underlain by limestones and is not the product of chemical dissolution, which is characteristic of limestone karst. They are the result of many years of physical, rather than chemical, erosion.
