Alagia Fieschi (died after 1334), also known as Alagia di Nicolò Fieschi and Alagia di Fieschi, was the daughter of Count Nicolò Fieschi and niece of Pope Adrian V. Alagia married Moroello Malaspina in the 1280s and they had five children. In Dante Alighieri's Divine Comedy, Alagia is remembered by Adrian V at the end of his conversation with Dante as the only virtuous woman in his family whom he wishes to pray on his behalf (Purgatorio, Canto XIX, 142-145). Alagia’s mention as the only virtuous person in her family reflects Dante’s view about Alagia's family's actions involving the Malaspina family. In addition, Alagia is celebrated by Dante through his portrayal of her as a virtuous woman whose prayer can contribute to Adrian V's journey of salvation.
