The Judicate of Logudoro or Torres was one of the four kingdoms or iudicati into which Sardinia was divided during the Middle Ages. It occupied the northwest part of the island from the 10th through the 13th century, bordering the Gallura to the east, Arborea to the south, and Cagliari to the southeast. Its original capital was Porto Torres. The region is still called Logudoro today.

The House of Malaspina was a noble Italian family of Longobard origin that descended from Boniface I, through the Obertenghi line, that ruled Lunigiana from the 13th to the 14th centuries, and the marquisate of Massa and lordship of Carrara since the 14th century.
