Kolkata district (formerly known as Calcutta district) is a district in the Indian state of West Bengal. It only contains the entire city proper of Kolkata, the capital city of the state and therefore it is a city district. It is the smallest district in the state and also the most densely populated district. Being a city district, the district itself is its own headquarters; it does not have further subdivisions like mahakumas or blocks that exist in all other districts of the state nor does it have a district magistrate. The sole local government of the whole district is Kolkata Municipal Corporation.
