Asirgarh Qila (, ) is an Indian fortress (qila) situated in the Satpura Range, about 20 km north of the city of Burhanpur, in Burhanpur District of Madhya Pradesh state. Because the fortress commands a pass through the Satpuras connecting the valleys of the Narmada and Tapti rivers, one of the most important routes from northern India to the Deccan,it was known as the "key to the Deccan". During Mughal Era, it was considered that Deccan starts from here: the empire from Asirgarh to Delhi was considered as Hindustan. The fort was built by Asa Ahir of the Ahir dynasty.
