Youjiang Zhuang, named after the Youjiang River in Guangxi, China, is a Northern Tai or Zhuang Language spoken in Tiandong County, Tianyang District, and parts of the Youjiang District in Baise, Guangxi.

André-Georges Haudricourt in 1956 included the language of Tianzhou, the county seat of Tianyang, under Dioi, his name for Northern Zhuang.

[2] Based on data from the 1950s Guangxi Zhuang language survey, Tiandong, Tianyang and a suburb of Baise City were grouped together.

In the 1999 A Study of Zhuang Dialects this group was referred to as the Youjiang language (右江土语),[3] and in 2007 Youjiang Zhuang was added as a separate language to Ethnologue.

[4] Youjiang Zhuang has two main writing systems, characters and romanization.
