Kamen Ariy, or Ary Rock, is an uninhabited islet of the Commander Islands in the North Pacific Ocean, east of the Kamchatka Peninsula in Eastern Russia. These islands belong to the Kamchatka Krai of the Russian Federation. Described as "craggy" by Encyclopædia Britannica, Kamen Ariy is about 8 kilometres west of Tufted Puffin Rock and consists of two rocks. The northern rock is pointed and reaches a height of 45 m (150 ft). The southern rock is much flatter and only reaches a height of 2.1 metres.
