Shan State is a state of Myanmar. Shan State borders China (Yunnan) to the north, Laos to the east, and Thailand to the south, and five administrative divisions of Myanmar in the west. The largest of the 14 administrative divisions by land area, Shan State covers 155,800 km2, almost a quarter of the total area of Myanmar. The state gets its name from Burmese name for the Tai peoples: "Shan people". The Tai (Shan) constitute the majority among several ethnic groups that inhabit the area. Shanland is largely rural, with only three cities of significant size: Lashio, Kengtung, and the capital, Taunggyi. Taunggyi is 150.7 km northeast of the nation's capital Naypyitaw.

The Shan language is the native language of the Shan people and is mostly spoken in Shan State, Myanmar. It is also spoken in pockets in other parts of Myanmar, in Northern Thailand, in Yunnan, in Laos, in Cambodia, in Vietnam and decreasingly in Assam and Meghalaya. Shan is a member of the Tai–Kadai language family and is related to Thai. It has five tones, which do not correspond exactly to Thai tones, plus a sixth tone used for emphasis. The term Shan is also used for related Northwestern Tai languages, and it is called Tai Yai or Tai Long in other Tai languages. Standard Shan, which is also known as Tachileik Shan, is based on the dialect of the city of Tachileik.
