Khasi is an Austro-Asiatic language spoken primarily in Meghalaya state in India by the Khasi people. Khasi is part of the Austroasiatic family of languages, and is fairly closely related to the Munda branch of that family, which is spoken in east–central India.

Although most of the 865,000 Khasi speakers are found in Meghalaya state, the language is also spoken by a number of people in the hill districts of Assam bordering with Meghalaya and by a sizable population of people living in Bangladesh, close to the Indian border.

Khasi is rich in folklore and folktale, and behind most of the names of hills, mountains, rivers, waterfalls, birds, flowers, and animals there is a story.

Khasi has significant dialectal variation. Several dialects have only partial mutual intelligibility, and Bhoi and Nonglung are distinct enough to be sometimes considered separate languages. Other dialects are Cherrapunji (Sohra), Khynrium, and War (not the same as the related War language); Cherrapunji and War are 75% similar lexically. Cherrapunji is standard.
