Khao Kho (Thai: เขาค้อ), is a 1143 m high mountain in Phetchabun Province, Thailand. It is in Khao Kho District. The mountain is part of the western range of the Phetchabun Mountains.

Khao Kho was named either after the Ceylon oak or after Livistona speciosa, a kind of palm tree. Both species are known as kho (Thai: ค้อ) in Thai and are abundant in the area.

A road leads to the summit where there is a memorial erected to commemorate the victims of the battles between the Royal Thai Armed Forces and insurgents of the Communist Party of Thailand. Between 1968 and 1981 there was unrest around the mountain where the provinces of Phetchabun and Phitsanulok meet.
