Olbia (IPA: [ˈɔlbja] or locally [ˈolbja]; Sardinian name: Terranoa, Gallurese: Tarranoa), is a town and comune of 56,231 inhabitants (2010) in northeastern Sardinia (Italy), in the Gallura sub-region.

Called Olbia in the Roman age, Civita in the Middle Ages (Giudicati period) and Terranova Pausania before the 1940s, Olbia was again the official name of the town after the period of Fascism.

Olbia (the name is of Greek origin) is very ancient and was possibly founded by the Punics, according to the archaeological findings. It contains ruins from Phoenician and Carthaginian settlement to the Roman Era, when it was an important port, and the Middle Ages, when it was the capital of the Giudicato of Gallura, one of the four independent states of Sardinia.
