Pa-Hng (also spelled Pa-Hung; 巴哼语 Bāhēng yǔ) is a divergent Hmongic (Miao) language spoken in Guizhou, Guangxi, and Hunan in southern China as well as northern Vietnam.

The Na-e dialect (also known by the Vietnamese rendition of Pa-Hng, Pà Then [Pateng]), is a geographic outlier.

Paul Benedict (1986) argued that it is not actually Pa-Hng, or even Hmongic, but a separate branch of the Miao–Yao language family.

[7] Jerold A. Edmondson has reported Pa-Hng dialects in Bac Quang District and Hong Quang Village of Chiem Hoa District in northern Vietnam, and found that they were most closely related to the Pa-Hng dialect spoken in Gaoji Township 高基, Sanjiang County, Guangxi.

In Vietnam, the Pa-Hng are an officially recognized ethnic group numbering around a few thousand people, where they are called Pà Thẻn.
