Udon Thani (อุดรธานี, also Udorn Thanee) is a city in the Isaan (Northeastern) region of Thailand. Often referred to as simply Udon or Udorn (อุดร), the city should not be confused with Ubon Ubon Ratchathani in southeastern Isaan. It is approximately 450 km (280 mi) northeast of Bangkok, and is the Capital City of the Province of this name.

Founded in the 1890s by Prince Prajak Silapakom, Udon Thani, with a population of about 230,000, is the 4th largest city in Thailand. Udon was home to a major USAF airbase during the Vietnam War that increased its wealth and importance. Surrounded by one of the major agricultural areas of the country, Udon Thani has become a regional hub for agriculture, commercial distribution, shopping and a fledgling tourism industry. Because of the U.S. presence (the airbase until 1976, a consulate until 1995, and, now, a Voice of America station) many Thais were well-paid and learned English, making them more marketable to foreign labour recruiters. Udon has a large number of its citizens who have or are working overseas, particularly in Middle East oilfields. This has contributed both to the wealth of the area and its desirability as an expat destination. More than 5,000 expats from Europe, Australia, and North America have settled in the area.
