Cabras (Sardinian: Crabas) is a comune (municipality) in the Province of Oristano in the Italian region of Sardinia, located about 90 kilometres (56 mi) northwest of Cagliari and about 6 kilometres (4 mi) northwest of Oristano.

Cabras borders the following municipalities: Nurachi, Oristano, Riola Sardo.

The municipal territory includes several beaches in the Sinis peninsula and on the Gulf of Oristano.

Cabras appeared in the 11th century, when the town of Tharros was abandoned due to raids from North African pirates.

Under the Giudicato of Arborea it had some importance as the court of the giudice (duke) was held in its castle.
