Reasi district is an administrative district in the Jammu division of Indian-administered Jammu and Kashmir in the disputed Kashmir region. The Reasi district is bordered by Udhampur district and Ramban district in the east, Jammu district in the south, Rajouri district in the west and by Kulgam district on the north. The Reasi and Rajouri tehsils formed a joint district called the "Reasi district" at the time of the princely state's accession to India in 1947. As part of the reorganisation, the two tehsils were separated and Reasi was merged with the Udhampur district. It again became a separate district in 2006.
