Iž is an island in the Zadar Archipelago within the Croatian reaches of the Adriatic Sea.

Island is nowadays also accessible to reach by car ferry; settlements are mutually connected by the state road that run between Veli Iž and island's ferry port located in cove "Bršanj" in Mali Iž; route construction started in early 1980's and ferry port construction started in 1988. Villages of Mali Iž are also connected to the main route with local roads.

Near the island there are some very small uninhabited islands: Knežak, Rutnjak and Fulija for example. In the Iž dialect people almost never say f, they use h instead. Main activities are sailing, fishing, olive cultivation and pottery. The island is very popular amongst foreign tourists, largely due to its great beaches.
