Alà dei Sardi (Sardinian: Alà) is a comune (municipality) in the Province of Sassari in the Italian region Sardinia, located about 160 kilometres (99 miles) north of Cagliari and about 35 kilometres (22 miles) southwest of Olbia.

Alà dei Sardi borders the following municipalities: Berchidda, Bitti, Buddusò, Monti, Olbia, Oschiri, Padru.

The ancient origins of Alà dei Sardi are testified by the numerous archaeological findings in the area.

The origin of the name has been connected to both the Balares and the Ilienses, two Sardinian people who lived in the area and had never totally been subdued by the Romans.

The modern Alà appeared in the 16th century, and has since then been traditionally connected to the breeding and agricultural activities.
