Dunay (Russian: Дунай, IPA: [dʊˈnaj]) is an urban locality (an urban-type settlement) under the administrative jurisdiction of the closed town of Fokino, Primorsky Krai, Russia, located on the coast of the Gulf of Peter the Great.

During the fall, the wheat was ground at a private mill, but it turned out to be too bitter to be eaten—a result of the fog and humidity in the region.

These goods were shipped to Vladivostok on sailboats to be sent to restaurants and bazaars, and the settlers received in exchange sugar, salt, matches, and other materials.

During the Civil War, a partisan detachment headed by Fyodor Usaty fought on the territory of the settlement.

The historical part of the settlement, known as Stary Dunay, is home to dachas where local villagers live.
