Bruu (also spelled Bru, B'ru, Baru, Brou) is a Mon–Khmer dialect continuum spoken by the Bru people of mainland Southeast Asia.
The distribution of the Bru language spreads north and northeast from Salavan, Laos, through Savannakhet, Khammouane, and Bolikhamsai, and over into neighboring Thailand and Vietnam (Sidwell 2005:11).

The following Bru subgroups are found in Quảng Bình Province (Phan 1998).
