Central Siberian Yupik (also known as Siberian Yupik, Bering Strait Yupik, Yuit, Yoit, "St. Lawrence Island Yupik", and in Russia "Chaplinski Yupik" or Yuk) is an endangered Yupik language spoken by the Indigenous Siberian Yupik people along the coast of Chukotka in the Russian Far East and in the villages of Savoonga and Gambell on St. Lawrence Island. The language is part of the Eskimo–Aleut language family.
In the United States, the Alaska Native Language Center identified about 400–750 Yupigestun speakers, considering "dormant speakers" who understand but cannot converse. In Russia in 2021, 172 people indicated that they speak the language, while only 92 of them use it in everyday life. Thus, the total number of speakers is no more than 550–900 people.
