The Khasi–Palaungic languages are a primary branch of the Austroasiatic language family of Southeast Asia in the classification of Sidwell (2011, 2018). This is a departure from Diffloth (2005) classification of Khasi-Khmuic with Khmuic and Mangic (Pakanic) now being separate branches within Austroasiatic family.

As per the classification of Sidwell (2011) and (2018), the Khasi–Palaungic languages are as follows:
