The Cemetery H culture was a Bronze Age culture in the Punjab region in the northern part of the Indian subcontinent, from about 1900 BCE until about 1300 BCE. It is regarded as a regional form of the late phase of the Harappan civilisation, but also as the manifestation of a first wave of Indo-Aryan migrations, predating the migrations of the proto-Rig Vedic people.
