Tambon is a local governmental unit in Thailand. Below district (amphoe) and province (changwat), they form the third administrative subdivision level. As of 2016 there were 7,255 tambons, not including the 180 khwaeng of Bangkok, which are set at the same administrative level, thus every district contains eight to ten tambon. Tambon is usually translated as "township" or "subdistrict" in English — the latter is the recommended translation, though also often used for king amphoe, the designation for a subdistrict acting as a branch of the parent district. Tambon are further subdivided into 69,307 villages (muban), about ten per tambon. Tambon within cities or towns are not subdivided into villages, but may have less formal communities called chumchon that may be formed into community associations.

An amphoe —usually translated as "district"—is the second level administrative subdivision of Thailand. Groups of amphoe or districts make up the provinces, and are analogous to counties. The chief district officer is Nai Amphoe. Amphoe are divided into tambons,, or sub-districts.
