Alirajpur (Hindi: अलीराजपुर जिला) is one of the 50 districts of Madhya Pradesh state in India. It was created from Alirajpur, Jobat and Bhabra tehsils of the former Jhabua district on 17 May 2008. Alirajpur is the administrative headquarters of the district. The district occupies an area of 2,165.24 square kilometres (836.00 sq mi), and at the 2011 census had a population of 728,677.
The district is named after its headquarters, Alirajpur, which was the capital of the former princely state of Ali Rajpur. The name of this town is derived by conjoining Ali (the fortress town and the former capital of the princely state founded by Anand Deo in 1437) and Rajpur (the latter capital).
Before the Indian independence in 1947, the Alirajpur State was under Bhopawar Agency sub-division of the Central India Agency. This principality was founded in 1437 and merged with the Indian Union after the Indian independence. The territory occupied by the present district became part of Madhya Bharat state in 1948 and subsequently became part of the re-organized Madhya Pradesh state on 1 November 1956.
