Cape Shelagsky or Cape Shelag (Russian: Мыс Шелагский; Ытрин|translit=Ytrin), also known as Erri by the Siberian Yupik,[1] is a headland situated in eastern Siberia, Russia on the shores of the East Siberian Sea.[2]
The cape was named after the Shelags, a little-known ethnic group that lived on the Arctic coast to the east of Cape Shelagsky.[3]
It is the eastern headland at the entrance of Chaun Bay. The cape is located at the western end of the Shelag Range, the northwesternmost subrange of the Chukotka Mountains.[4]
