The Port of Kolkata is a riverine port in the city of Kolkata, India. It is the oldest operating port in India, having originally been constructed by the British East India Company.
The Port has two distinct dock systems - Kolkata Docks at Kolkata and a deep water dock at Haldia Dock Complex, Haldia.
In the 19th century Kolkata Port was the premier port in British India. After independence its importance decreased because of factors including the Partition of Bengal (1947), reduction in size of the port hinterland and economic stagnation in eastern India. In the 21st century due to the east Indian economic recovery and infrastructure improvements, the port grew swiftly to become the nation's third largest container port. It was one of India's fastest growing ports in 2004-05.
