The Alaska North Slope is the region of Alaska in the United States located on the northern slope of the Brooks Range along the coast of the Arctic Ocean. The region contains the major petroleum reserves of Alaska, until the field discovered in 1968 at Prudhoe Bay, as well as the Arctic National Wildlife Refuge, which itself has been the subject of controversy surrounding the possibility of petroleum drilling within its boundaries. The petroleum extracted from the region is transferred south by means of the Trans-Alaska Pipeline System to Valdez on the Pacific Ocean.
Much of the region is located in the North Slope Borough.
