The Sea of Okhotsk is a marginal sea of the western Pacific Ocean. It is between the Kamchatka Peninsula on the east, the Kuril Islands on the southeast, the island of Hokkaidō to the south, the island of Sakhalin along the west, and a long stretch of eastern Siberian coast along the west and north. The northeast corner is Shelikhov Gulf. It is named after Okhotsk, the first Russian town in the Far East.
