Haroonabad or Harunabad (Punjabi, Urdu: ہارون آباد) is a town in Bahawalnagar District of the Punjab Province of Pakistan.

It was laid out and established as a Mandi Town under the Satluj valley project during the colonization of the region under the English rule in the second decade of the 20th century.

Other castes in the region were Seraiki Jats, Baloch, Meghwals/Hindu Vankar, Bishnois and Jains[4] In 1927, the branch railway line linking Fortabbas town with Bahawalnagar city was constructed.

The establishment of irrigation system/canal system under the Satluj valley project in 1934 added to the agricultural production of the hinterland and provided a significant economic base to this small settlement.

A large number of Muslim refugees especially from Malwa region of Punjab and Haryana, mainly Arains, Rajputs and Julahas settled here and the population of the town was substantially increased.

Development of some residential colonies, establishment of social services like educational and health institutions and provision of public utilities made living conditions in the town more attractive and resulted in rapid growth.
