The Tai Noi or Lao Buhan script is a Brahmic script that has historically been used in Laos and Isan since about 1500 CE. The contemporary Lao script is a direct descendant and has preserved the basic letter shapes. The script has mostly dropped out of use in the Isan region of Thailand, due to the Thaification policies of the Thai government, that imposed Central Thai culture such as the Thai script throughout the country.

The Brahmic scripts, also known as Indic scripts, are a family of abugida writing systems. They are used throughout the Indian subcontinent, Southeast Asia and parts of East Asia. They are descended from the Brahmi script of ancient India and are used by various languages in several language families in South, East and Southeast Asia: Indo-Aryan, Dravidian, Tibeto-Burman, Mongolic, Austroasiatic, Austronesian, and Tai. They were also the source of the dictionary order (gojūon) of Japanese kana.
