The Phetchabun mountains (Thai: ทิวเขาเพชรบูรณ์, RTGS: Thio Khao Phetchabun, pronounced [tʰīw kʰǎw pʰét.t͡ɕʰā.būːn]) are a mountain massif in Phetchabun, Phitsanulok, Loei and Chaiyaphum Provinces, Thailand. It consists of two parallel mountain chains, with the valley of the Pa Sak River in the middle.

The strange rock formations of Phu Hin Rong Kla and fields where the Siam tulip flower (Curcuma alismatifolia), known as dok krachiao (ดอกกระเจียว) in Thai, grows wild are some of the characteristics of the Phetchabun Mountains.
