Divide County is a county located in the U.S. state of North Dakota. As of the 2010 census, the population was 2,071. Its county seat is Crosby.

Divide County was formed following a vote at the November 1910 general election to divide Williams County into two counties. This division is the most likely origin of the name, though additional deciding factors may have been the fact that Divide County lies on the continental divide between the watersheds that flow into the Gulf of Mexico and those that flow into Hudson Bay. This county lies on boundaries between the United States and the Canadian border of Saskatchewan. The county government was first organized on December 9, 1910; Crosby has always been the county seat.
