Cooperstown is a city in Griggs County, North Dakota, United States.

The city is named for R. C. Cooper, a bonanza farmer who built the first wood-frame house in the area in 1880.

Prior to Cooper's arrival, most settlers or the era lived in sod houses, covered wagons, tents, or log cabins (especially near the Sheyenne River where trees were numerous).

The residents of Hope were determined that the county seat be located in their town and refused to surrender the records to Cooperstown.

Sometime the following month, an armed party from Hope overpowered three guards in the new county office and returned the records to their town.

Hope returned Griggs County's record to Cooperstown after an election on June 2, 1883.
