Phu Hin Rong Kla National Park (Thai: อุทยานแห่งชาติภูหินร่องกล้า, RTGS: Utthayan Haeng Chat Phu Hin Rong Kla) is a national park located in the Loei and Phitsanulok Provinces of Thailand.

The park was the base of operations of the long fight of Thai combatant in communist war of Thailand.

Phu Hin Rong Kla National Park is located 50 kilometres (31 mi) north of Phetchabun town and 80 kilometres (50 mi) east of Phitsanulok town in the Nakhon Thai district of Phitsanulok Province and Dan Sai district of Loei Province with an area of 191,875 rai ~ 307 square kilometres (119 sq mi)[5] and is neighbouring Khao Kho National Park to the southeast.

Due to the difficult terrain, it was initially impossible to achieve success against the communists and tactics had to be changed.

Later the Royal Forest Department proposed to include Phu Hin Rong Kla in the system of national parks on March 15, 1983.
