Roi Et (Thai: ร้อยเอ็ด, pronounced [rɔ́ːj ʔèt]) is one of Thailand's seventy-six provinces (changwat) lies in central northeastern Thailand also called Isan. Neighboring provinces are (from north clockwise) Kalasin, Mukdahan, Yasothon, Sisaket, Surin, and Maha Sarakham.


The name of the province literally means 'one hundred and one' (Thai: ร้อยเอ็ด; RTGSroi et ). Correctly, the number should be "eleven" (Thai: สิบเอ็ด; RTGSsip et ), as the province was named after its eleven ancient gates built for its eleven vassal states. In ancient times, the number "eleven" was written "๑๐๑" (101) and the provincial name was written accordingly. Later, people took "๑๐๑" to mean 'one hundred and one' and have since then called it "Roi Et".[5]


Most of the province is covered by plains about 130–160 meters above sea level, drained by the Chi River. In the north are the hills of the Phu Phan mountain range. The Yang River is the major watercourse. In the south is the Mun River, which also forms the boundary with Surin. At the mouth of the Chi River, where it enters the Mun River, a floodplain provides a good rice farming area. The total forest area is 346 km2 (134 sq mi) or 4.4 percent of provincial area.[1]


The area was already settled at the time of the Khmer empire, as several ruins show. However, the main history of the province began when Lao people from Champasak settled near Suwannaphum during the Ayutthaya Kingdom.[citation needed] In the late-18th century, King Taksin moved the city to its present site, then called Saket Nakhon.[6]


The provincial seal shows the shrine of the city pillar, which is in the artificial lake Bueng Phalan Chai. The spirit of the shrine, Mahesak, is revered by local people.

The provincial tree is Lagerstroemia macrocarpa.



Route 214 leads north to Kalasin and south to Kaset Wiset, Surin, and Prasat. Route 2044 leads east to Phon Thong. Route 23 leads west to Maha Sarakham and Ban Phai, and east to Yasothon and Ubon Ratchathani. Route 215 leads south to Suwannaphum and the border with Surin province.


Roi Et is served by Roi Et Airport to the north of the town.[7]Thai AirAsia operates daily flights to Don Mueang Airport 470 kilometers away.


Roi Et's main hospital is Roi Et Hospital, a regional hospital operated by the Ministry of Public Health.
