Lawu (autonym: la21 wu21)[2] is a highly endangered unclassified Loloish language of Yunnan, China.
It has about 50 elderly speakers in Jiuha village 旧哈村,[3] Shuitang district 水塘镇, Xinping County, Yuxi Prefecture, Yunnan Province.
There are possibly also some speakers in Jiujia District 九甲乡, Zhenyuan County, Pu'er Prefecture, Yunnan Province.
Andrew Hsiu (2017)[5] suggests that Lawu is related to Awu of Xiaopingzi 小坪子, Daping Township 大坪乡, Yuanyang County, Yunnan, China,[6] which is documented in Lu & Lu (2011).
Lewu, which is currently extinct, may have been related to Lawu, but classification is uncertain due to the paucity of data.
