Tai Dam (simplified Chinese: 傣担语; traditional Chinese: 傣擔語; pinyin: Dǎidānyǔ), also known as Black Tai (Thai: ภาษาไทดำ; pronounced [pʰāː sǎː tʰāj dām]; Vietnamese: tiếng Thái Đen; 'Black Tai language'; simplified Chinese: 黑傣语; traditional Chinese: 黑傣語; pinyin: Hēidǎiyǔ), is a Tai language spoken by the Tai Dam in Vietnam, Laos, Thailand, and China (mostly in Jinping Miao, Yao, and Dai Autonomous County).

In particular, the Khmer, Pali and Sanskrit additions to Thai and Lao (Isan) are largely missing from Tai Dam.
