Arbatax (Italian pronunciation: [ˈarbataks]) is the greatest hamlet (frazione) of Tortolì, Sardinia, in Italy. With almost 5,000 inhabitants, it is also the third town in its province (Ogliastra) by population, after Lanusei municipality (5,700) and Tortolì proper  (5,300).
The origin of the name Arbatax is uncertain, according to the tradition it would derive from the Arabic for "14th Tower" and refers, probably, to the nearby watchtower built by the Spaniards to protect the territory from the incursion of Arab pirates. 
The location assumed importance in the 1960's after the construction of the main Sardinian Paper Mill.
The port is used by ferries from Civitavecchia and is also monopolized by the marine construction company Intermare, who build gas rigs and vessels. The marina is one of the cheapest in Sardinia and provides an excellent base for exploring the Eastern coastline.
The closest airport is the Tortolì Airport, far about 4km from the town.
Mussels are farmed in the nearby lagoon and fresh fish are on sale from the fishing cooperative. The red rocks are a tutist attraction.
