Ranga Reddy district was formed on 15 August 1978 by carving out some portions of Hyderabad urban Taluk and the merger of the entire rural and urban areas of the remaining Taluks of erstwhile Hyderabad district. Ranga Reddy district is primarily the rural hinterland for twin cities of Hyderabad and Secundrabad feeding the powerful commercial centre with various raw materials, agriculture produce and finished products.
Name of the district was Hyderabad (Rural) to begin with. It was changed to ‘K.V. Ranga Reddy’, and later to ‘Ranga Reddy’ district, the former Deputy Chief Minister of Andhra Pradesh.
The District is located in the central part of the Deccan Plateau and lies between 160 30` and 180 20` of North Latitude and 770 30` and 790 30` of East Longitudes.
