Morang is a district on the southern Tarai, or plains, of Eastern Nepal. Most of the land is taken up by rice and jute cultivation, though areas of Sal forest remain along the northern part of the district where the plains meet the hills. A large amount of the forest was cleared in the last century, and in the process, many settlers migrated to the district from the hills and India.

Most of the district is rural, though it is also home to Biratnagar, the second largest city in Nepal. Other minor towns include Dhubi and Rangeli. A large number of regularly spaced weekly markets and small bazaars serve the trading needs of one of the most densely populated parts of the country.
