Ranghar are a Muslim ethnic group, which is found in Sindh and Punjab provinces of Pakistan and Haryana, Himachal Pradesh, Delhi and Uttar Pradesh states of India. The term Ranghar is very rarely used by the community itself, who prefer the self-designation Muslim Rajput.
In Haryana, the Ranghar spoke a dialect of their own, called Ranghari, which is itself a dialect of Haryanvi, and many in Pakistan still use the language. Those of Uttar Pradesh speak Khari Boli among themselves, and Urdu with outsiders. After the formation of Pakistan in 1947, many Uttar Pradesh Ranghars also migrated to Punjab and Sindh in Pakistan. They are entirely Sunni Hanafi Muslims and follow Deobandi and Barelvi schools of South Asia.
