Narayanganj is a city in central Bangladesh in the Greater Dhaka area. It is in the Narayanganj District, about 16 km (10 mi) southeast of the capital city of Dhaka. With a population of almost 1 million, it is the 6th largest city in Bangladesh. It is also a center of business and industry, especially the jute trade and processing plants, and the textile sector of the country. It is nicknamed the Dundee of Bangladesh, due to the presence of its many jute mills.

Greater Dhaka is the Megalopolis including and surrounding the Bangladeshi capital city of Dhaka, which has grown into one of the world's largest megacities, and shows a very rapid rate of expansion. Dhaka not only grows because it is the capital and largest urban center but also due to massive internal displacement from millions of people living in a perennially flood-prone river delta.
