Phu Kradueng (Thai: ภูกระดึง, pronounced [pʰūː krādɯ̄ŋ]) is a district (amphoe) of Loei province, northeastern Thailand.

The minor district (king amphoe) was created on 1 January 1962, when the three tambons, Si Than, Puan Phu, and Pha Khao, were split off from Wang Saphung district.

[2] The district is divided into four sub-districts (tambons), which are further subdivided into 54 villages (mubans).

Phu Kradueng is a township (thesaban tambon) which covers parts of tambons Si Than, Pha Nok Khao, and Phu Kradueng.

Missing numbers are tambons which now form the Districts Pha Khao and Nong Hin.
