Colonel William A. Phillips

North Dakota's at-large congressional district is the sole congressional district for the state of North Dakota. Based on size, it is the eighth largest congressional district in the nation.

The district is currently represented by Kelly Armstrong.

History

The district was first created when North Dakota achieved statehood on November 2, 1889, electing a single member. Following the 1900 United States census the state was allocated two seats, both of whom were elected from an at large district. Following the 1910 United States census a third seat was gained, with the legislature drawing three separate districts. The third district was eliminated after the 1930 United States census. After the third seat was lost, North Dakota returned to electing two members at-large (statewide).

Following the 1960 United States census two separate districts were created. In 1970, the second district was eliminated following the 1970 United States census and a single at-large district was created. Since 1972, North Dakota has retained a single congressional district.
