The Walrus Islands are made up of seven small islands, a group of craggy coastal islands in the Bering Sea, close to the northern shores of Bristol Bay, Alaska, United States at the entrance to Togiak Bay.

The islands are protected as the Walrus Island State Game Sanctuary, and managed by the Alaska Department of Fish and Game. In 1968, the Walrus Islands were designated as a National Natural Landmark by the U.S. National Park Service. The area covers 9,187 acres (3,718 ha).

The name of the islands was earned because of the immense concentration of walruses in the adjacent waters of these islands every summer. The largest concentration of walruses occurs at Round Island where 14,000 male walruses have been observed on a single day.

As part of the Walrus Islands, Round Island also contains a copious record of archaeological evidence of human occupation dating back to the Norton Tradition 6,000 years ago. This was approximately the same time that the Bering Sea level rose to separate the islands from the mainland of contemporary Alaska. The Norton Tradition was an archaeological culture that used flake-stone tools and brought new technologies to the islands including oil-burning lamps and clay vessels for use.
