The Central Alaskan Yup’ik are an Alaska Native people of western and southwestern Alaska, ranging from the Norton Sound down along the coast of the Bering Sea (including on Nelson Island and Nunivak Islands) to Bristol Bay as far south as the Alaska Peninsula at Naknek River and Egegik Bay. They are also known as Cup’ik by people of Nunivak Island.

The Yup’it are the most numerous of the various Alaska Native groups and speak the Central Alaskan Yup’ik language, a member of the Eskimo–Aleut family of languages. Today, the Yup’ik generally work and live in western style but still hunt and fish in traditional subsistence ways and gather traditional foods.
