Alaska North Slope
Landsat 7 false-color image of the North Slope. Along the coast, fast ice still clings to the shore in a solid, frozen sheet. At the top of the scene is the drifting sea ice. A dark blue strip of open water, known as a flaw lead, separates the fast ice from the drifting sea ice. The Brooks Range is visible at the bottom. (June 2001)

The Alaska North Slope is the region of the U.S. state of Alaska located on the northern slope of the Brooks Range along the coast of two marginal seas of the Arctic Ocean, the Chukchi Sea being on the western side of Point Barrow, and the Beaufort Sea on the eastern.

The region contains the National Petroleum Reserve–Alaska, with the bulk of Alaska's known petroleum until the Prudhoe Bay Oil Field was discovered in 1968, 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.

Within the North Slope, only a surface "active layer" of the tundra thaws each season; most of the soil is permanently frozen year-round. On top of this permafrost, water flows to sea via shallow, braided streams or settles into pools and ponds. Along the bottom of the Landsat 7 image on the right the rugged terrain of the Brooks Range mountains is snow-covered in places (blue areas) and exposed (pink areas) in others.

Much of the region is located in North Slope Borough.
