Phetchabun (Thai: เพชรบูรณ์) is one of the northern provinces (changwat) of Thailand.
Phetchabun is located in the lower northern region of Thailand, in the area between the northern and the central region.
The province lies in the broad fertile river valley of the Pa Sak River, with mountains of the Phetchabun mountain range to the east and west. It is surrounded by places of interest, many well-known national parks, beautiful waterfalls and great lakes.
The word Phetcha originates from the Sanskrit word vajra meaning "diamond" (or weapon of Indra), and the word bun from Sanskrit purna meaning "full", "perfect" or "whole". Hence the name of the province literally means "Perfect Diamond".
Initially, the province was called "Phe-cha-buth" as "Phuenchapura", which means the city that is plenty of crops. The reason for being given such name is because the province is very fertile and full of natural resources. Because of the fertility of the land, Phetchabun has always been an agriculturally productive area.
The provincial seal show a diamond on a mountain, as diamonds are found in the province. In the front are tobacco plants as one of the crops grown in the province.
The provincial tree is the Tamarind (Tamarindus indica).
