Arzachena is a town and comune in the province of Sassari, northern Sardinia, the second largest island off the coast of Italy. Arzachena lies half way between the original Costa Smeralda resort and Porto Rafael, both founded in the late 1950s. After Olbia and Tempio Pausania, it is the third largest commune in Gallura by inhabitants.
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.
