Districts of Odisha

Odisha, located on the eastern coast of India, currently comprises 30 administrative districts. When the province of Odisha was officially formed on April 1, 1936, it began with just five districts. Over time, to improve administrative efficiency and ensure better governance, the state underwent multiple reorganizations leading to the creation of new districts. Today, each of the 30 Districts of Odisha functions as an individual administrative unit, managed by a District Magistrate (DM) and Collector who oversee law and order, revenue collection, and development programs.
