The Dai people are several Tai-speaking ethnic groups living in the Xishuangbanna Dai Autonomous Prefecture and the Dehong Dai and Jingpo Autonomous Prefecture of China's Yunnan Province. The Dai people form one of the 56 ethnic groups officially recognized by the People's Republic of China. By extension, the term can apply to groups in Laos, Vietnam, Thailand and Myanmar when Dai is used to mean specifically Tai Yai, Lue, Chinese Shan, Tai Dam, Tai Khao or even Tai in general. For other names, see the table below.

Lao, sometimes referred to as Laotian, is the official language of Laos and a significant language in the Isan region of northeastern Thailand, where it is usually referred to as the Isan language. Spoken by over 3 million people in Laos and 3.2 million in all countries, it serves as a vital link in the cultural and social fabric of these areas. It is written in the Lao script, an abugida that evolved from ancient Tai scripts.
