Tambon (, ) is a local governmental unit in Thailand. Below district ( amphoe) and province ( changwat), they form the third administrative subdivision level. As of 2009 there were 7,255 tambon, not including the 169 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 (Thai: "king") 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 ( ชุมชน) that may be formed into community associations.
