The Arora is a community of the Punjab region closely related to the Khatri community. Aroras were mainly concentrated in West Punjab in modern Pakistan along the banks of the Indus River and its tributaries; in the Malwa region in East Punjab in India, although not greatly in what became the Khyber Pakhtunkhwa from 1901; in Sindh (mainly as Sindhi Aroras but there were many Punjabi and Multani speaking Aroras as well); in Rajasthan (as Jodhpuri and Nagauri Aroras/Khatris); and in Gujarat. In post-independence India, Aroras mainly reside in Punjab, Haryana, Himachal Pradesh, Delhi, Jammu, Rajasthan, Uttar Pradesh, Uttarakhand, and Gujarat.
