Pak Chom (Thai: ปากชม, pronounced [pàːk t͡ɕʰōm]) is the northeasternmost district (amphoe) of Loei province, northeastern Thailand.

The minor district (king amphoe) Pak Chom was created on 1 September 1967, when the three tambons, Pak Chom, Hat Khamphi, and Chiang Klom, were split off from Chiang Khan district.

The important water resources are the Mekong and Chom Rivers.

The district is divided into six communes (tambons), which are further subdivided into 50 villages (mubans).

Pak Chom and Chiang Klom each cover parts of the same-named tambons.
