Yttygran Island (Russian: Итыгран; Eskimo–Aleut: Siklyuk) is an island in the Bering Sea 24 kilometres (15 miles) northwest of Cape Chaplino, close to the coast of Chukotka.

Nowadays this island is popular with ecotourists. Beluga whales are common in the waters around Yttigran and neighbouring Arakamchechen islands.
