The Free Municipality of Sassari or Republic of Sassari was a state in the region of Sassari in Sardinia during the 13th and 14th centuries, confederated first with the Republic of Pisa as a semi-autonomous subject and later with the Republic of Genoa as a nominally independent ally. It was the first and only independent city-state of Sardinia during the early renaissance.
