Six-region division system

Four-region division system

Meteorological division system

Thailand is variably divided into different sets of regions, the most notable of which are the six-region grouping used in geographic studies, and the four-region grouping consistent with the Monthon administrative regional grouping system formerly used by the Ministry of Interior. These regions are the largest subdivisions of the country.

In contrast to the administrative divisions of the provinces of Thailand, the regions no longer have an administrative character, but are used for statistical or academic purposes.
