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 (Indus Valley) civilisation (alongside the Jhukar culture of Sindh and Rangpur culture of Gujarat), but also as a phase of the Indo-Aryan migrations[citation needed].
