Cape Denbigh is located on the Seward Peninsula in Eastern Norton Sound in the U.S. state of Alaska. It is notable for the Iyatayet Site, an Archaic Stage hunter gather archaeological site. The headland is a moderately high, rounded hill, joined to the mainland by a low, narrow neck. The head of the bight, eastward of the cape, is shoal, but in approaching the water shoals gradually. A good anchorage in northeasterly winds can be had eastward of the cape.
