The Fortuna–Oungre Border Crossing connects the towns of Fortuna, North Dakota and Oungre, Saskatchewan on the Canada–US border.

It is located along the CanAm Highway: U.S. Route 85 on the American side and Saskatchewan Highway 35 on the Canadian side.

It is the westernmost border crossing in the state of North Dakota.

It is a lightly-used crossing with the reduction in local population due to agricultural automation and the 1984 closure of the Fortuna Air Force Station.
