Rab [ɾâːb] is an island in the "Primorsko-goranskoj županiji" region in Croatia, located just off the northern Croatian coast in the Adriatic Sea.

[2] The main settlement on the island is the eponymous town of Rab, although the neighboring village of Palit has the biggest population.

Its Medieval Dalmatian-speaking population used Arbe, Arbia, Arbiana, Arbitana and most frequently Arbum in the documents written in the Latin.

In Croatian it became Rab, a form which probably goes back as far as the 7th century[dubious – discuss] when the Slavs began to settle on the island.

By the papal bull Locum Beati Petri of 30 June 1828, the history of the diocese as a residential see came to an end and its territory was united with that of Krk.

During World War II, the forces of Fascist Italy established the Rab concentration camp on the island.

After the Second World War, the island was part of the Socialist Federal Republic of Yugoslavia until the Croatian independence referendum in 1991.

The island of Rab is rich in cultural heritage and cultural-historical monuments that make it a popular vacation destination.
