The Tai Le script (ᥖᥭᥰ ᥘᥫᥴ, [tai˦.lə˧˥]), or Dehong Dai script, is a Brahmic script used to write the Tai Nüa language spoken by the Tai Nua people of south-central Yunnan, China. (The language is also known as Nɯa, Dehong Dai and Chinese Shan.) It is written in horizontal lines from left to right, with spaces only between clauses and sentences.

The Tai Le script is approximately 700–800 years old and has used several different orthographic conventions.

The traditional Tai Le script is a Brahmic script that is found in the Dehong Dai and Jingpo Autonomous Prefecture of Yunnan, China.

The script is known by a variety of names. It is known as Lik Tho Ngok (Tai Nüa: lik4 tho2 ŋɔk4, "bean sprout script") by the Tai Nua, the Old Tay or Old Dai script, Lik Tay La/Na (Tai Nüa: lik6 Tay2 lä1/nä1, "Northern Tay script") and Lik To Yao (Tai Nüa: lik6 to4 yaaw2, "long script").

The Lik Tho Ngok script used by the Tai Nuea people is one of a number of "Lik Tai" scripts or "Lik" scripts used by various Tai peoples in northeastern India, northern Myanmar, southwestern Yunnan, and northwestern Laos. Evidence suggests that the Lik scripts have a common origin from an Old Burmese or Mon prototype before the fifteenth century, most probably in the polity of Mong Mao. The Lik Tai script featured on a 1407 Ming dynasty scroll exhibits many features of the Burmese script, including fourteen of the nineteen consonants, three medial diacritics and the high tone marker. According to the scholar Daniels, this shows that the Tai borrowed from the Burmese script to create their own script; the Lik Tai script was derived from the Burmese script, as it could only have been created by someone proficient in Burmese. Daniels also argues that, unlike previously thought, the Lik Tho Ngok script is not the origin of the other Lik Tai scripts, as the 1407 Lik Tai script shows greater similarity to the Ahom script, which has been attested earlier than the Lik Tho Ngok script. Other "Lik" scripts are used for the Khamti, Phake, Aiton and Ahom languages, as well as for other Tai languages across Northern Myanmar and Assam, in Northeast India. The Lik scripts have a limited inventory of 16 to 18 consonant symbols compared to the Tai Tham script, which possibly indicates that the scripts were not developed for writing Pali.

It is unknown when, where and how the Lik Tho Ngok script first emerged, and it has only been attested after the 18th century. Broadly speaking, only Lik Tho Ngok and Lik To Mon ('round' or 'circular' script), used in Shan State, are still in use today. Government-led reforms of the main Tai Nuea traditional scripts began in Dehong the 1950s. Between 1952 and 1988 the Dehong script went through four reforms, initially adding a consonant, vowel symbols and tone markers, then in 1956 changing many graphemes and tone markers. A third reform was proposed in 1964, again adding and changing graphemes and making further changes to tone markers, and a fourth reform took place in 1988.

In common with other Lik orthographies, Lik Tho Ngok is an alphasyllabary, but not fully an abugida, since occurrence of an inherent vowel is restricted to medial position, where it may take either /-a-/ or /-aa-/.

In Mueng Sing today, the smaller glyphs are not used and two main styles of Lik Tho Ngok are recognised by local scribes: To Lem (Tai Nüa: to1 lem3 ‘edged letters,’) which have straighter edges and more pointed angles, and To Mon (Tai Nüa: to1 mon4 ‘rounded letters’) without sharp angles. There are 21 initial consonant graphemes in the Lik Tho Ngok script used in Mueang Sing, representing 15 phonemes in the spoken dialect plus two rarer phonemes (/d/ and /b/).
