Boriwen (Thai: บริเวณ) were subdivisions of three of the larger Thai monthon. Several mueang were grouped together into one boriwen. In 1908 the boriwen were renamed to changwat,[1] which became the name of provinces countrywide in 1916.[2]

The monthon with between three and five boriwen were Phayap, Udon Thani and Isan. Each boriwen was administrated by a commissioner (khaluang boriwen, ข้าหลวงบริเวณ). The administrative headquarters of the boriwen were located in the provincial town listed first:
