Joanna of Gallura (..., c. 1291 – Florence, 1339), also known as Giovanna Visconti, was the last titular Judge (giudicessa) of Gallura. Joanna claimed her rights in Sardinia to no avail and eventually sold them to her relatives, the Visconti of Milan, who later sold them to the Crown of Aragon. She is mentioned passingly by Dante Alighieri in the Divine Comedy. Her father, a friend of Dante's, but consigned to Purgatory with the other negligent rulers, asks her to be reminded of him.
