Jacopo Alighieri (1289–1348) was an Italian poet, the son of Dante Alighieri, whom he followed in his exile. Jacopo's most famous work is his sixty-chapter Dottrinale.
He was exiled from Florence with his father and brothers Giovanni and Pietro in 1315. He subsequently traveled to Ravenna, where he may have lived with his father. Dante died in 1321, and Jacopo sent a copy of the Divine Comedy to Guido da Polenta, the lord of the city. In 1325, he returned to Florence, where he took minor orders, making it possible for him to become a canon in Verona. At home, he took charge of his family's financial affairs; in 1343, he was able to retake possession of his father's confiscated property. In his later years, he had a troubled relationship with Jacopa di Biliotto degli Alfani, with whom he had a daughter named Alighiera and a son named Alighiero.
