Islamgarh (Urdu: اسلام گڑھ ) is a tehsil and Municipal Committee of Mirpur District near Mangla Dam of Azad Jammu and Kashmir.

The Punjab region became predominantly Muslim due to missionary Sufis whose dargahs dot the landscape of Kashmir.

After the decline of the Mughal Empire, the Sikhs overran the region and later Dogra invaded and occupied Mirpur District.

After the independence of Pakistan in 1947, the minority Hindus and Sikhs migrated to India while Muslim refugees from Jammu division settled down in the Mirpur District.

Rapid progress and fast growing population gave Islamgarh the status of town committee in 1979 and after attaching the union council Andrah Klan and village Kalyal Bainsi to Islamgarh, its status was raised to Municipal Committee in 1998.

The population of area will increase if proposed bridge is constructed between Rathoa Muhammad Ali and Chak Haryam.

Now due to Mangla Dam raising project, the people of adjoining villages (Chak Haryam, Andrah Klan, Bajar, Bandor, Lakhora, part of Kalyal Bainsi and Jammuie villages have sacrifice their homes and land.

The trust is a registered Non-Governmental Organisation (NGO) in Pakistan and serves the health needs of the local population.
