The Khasi Hills (/ˈkɑːsi/) are a low mountain formation on the Shillong Plateau in the Meghalaya state of India. The Khasi Hills are part of the Garo-Khasi-Jaintia range and connect with the Purvanchal Range and the larger Patkai Range further east. The Khasi Hills, and the whole Garo-Khasi-Jaintia range, are in the Meghalaya subtropical forests ecoregion.
The Khasi Hills, and the entire Meghalaya state, was administratively part of Assam before 1970. In older sources in particular, the alternative transcription Khasia Hills is seen.
