Mukdahan (มุกดาหาร) is a city in Isaan.
Mukdahan is the 73rd province of Thailand. Its history dates from the late Ayutthaya period, over 200 years ago. At first, on the left side of the Mekong River, there was a large community called Ban Luang Phon Sin located by Phrathat Ing Hang, presently in Savannakhet Province of Lao PDR. The community was ruled by Chao Chan Suriyawong. His son was Chao Kinnari. He later built a new town at the mouth of Huai Muk on the right bank of the Mekong River in 1767. The town was completed in 1770 and named "Mukdahan" (moonstone or pearl) according to a propitious sign occurring to him while the town was under construction. That is why the locals call the town "Mueang Muk".
During the reign of King Taksin the Great, Chao Kinnari was promoted as Phraya Chanthon Si Surat Upparacha Manthaturat to be the first ruler of Mukdahan in 1778.
At first, Mukdahan was part of 'Monthon Udon' or Udon Circle. In 1907, the Circle was dissolved to become a province and Mukdahan was then an Amphoe of Nakhon Phanom province. It was promoted as Mukdahan province in 1982 as the country’s 73rd province and the 17th province of Isaan.
Actually, Mukdahan is a significant gateway to Indochinese countries. The local people of Mukdahan actually have had a long relationship with the people in Savannakhet province of Laos. Although they are apart by the 70 km long Mekong River. Mukdahan is home to 8 ethnic minorities; namely, Thai Isan, Phu Thai, Thai Kha, Kraso, Thai Kaloeng, Thai Yo, Thai Saek, and Thai Kula. It has abundant natural beauty. Mukdahan covers a total area of 4,339.830 sq km.

Go next 
Roughly 4 km north of each city's centre, the Second Thai-Lao Friendship Bridge  connects Mukdahan with the Lao city of Savannakhet on the opposite side of the Mekong River. There is a regular bus connection between the cities; a one-way ticket costs 100 baht. While there is no formal bus stop at either end of the bridge, passengers need to disembark for the border formalities on both sides; hence in practice it's possible to buy a ticket and board the bus on the border if you've arrived there by other means.
There is a car park on the Mukdahan side of the bridge, one night's parking costs 100 baht. With the correct paperwork it's also possible to drive your car over to Laos. There are no pedestrian lanes on the bridge.
Visa-on-arrival is available at the border post for those nationalities that require one (see the article on Laos for more details). Additionally, the Lao border officials charge an "entry fee" (40-170 baht), "exit fee" (40 baht) and after 16:00, an "overtime fee" (40 baht) for stamping one's passport.
