Arzachena (Italian pronunciation: [artsaˈkɛːna]; Gallurese: Alzachèna; Sardinian: Altzaghèna) is a town and comune (municipality) in the Province of Gallura North-East Sardinia in the northeastern part of the autonomous region of Sardinia, the second largest island of Italy. Arzachena lies halfway between the original Costa Smeralda resort and Porto Rafael, both founded in the late 1950s. After Olbia and Tempio Pausania, it is the 3rd-largest commune in Gallura by population, with 13,435 inhabitants as of 2025.

The frazione of Porto Cervo is the main resort area of Costa Smeralda for summer tourism, which since the 1960s has replaced agriculture as the main local source of economic activity. Nearby there are numerous archaeological sites from the Nuragic period, including those from a local sub-culture known as Arzachena culture (the necropolis of Li Muri and others).
