The North Dakota Democratic–Nonpartisan League Party is the North Dakota affiliate of the national Democratic Party. It was formed as the outcome of a merger of two parties; the state previously had a three-party political system. It is one of only two state Democratic Party affiliates to have a different name from the central party, the other being the neighboring Minnesota Democratic–Farmer–Labor Party. The party currently has very weak electoral power in the state, controlling none of North Dakota's statewide or federal elected offices.

North Dakota is a landlocked U.S. state in the Upper Midwest, named after the indigenous Dakota Sioux. It is bordered by the Canadian provinces of Saskatchewan and Manitoba to the north and by the U.S. states of Minnesota to the east, South Dakota to the south, and Montana to the west. North Dakota is part of the Great Plains region, characterized by broad prairies, steppe, temperate savanna, badlands, and farmland. North Dakota is the 19th largest state, but with a population of less than 780,000, it is the 4th least populous and 4th most sparsely populated. The state capital is Bismarck while the most populous city is Fargo, which accounts for nearly a fifth of the state's population; both cities are among the fastest-growing in the U.S., although half of all residents live in rural areas.
