Federico Fieschi

Federico Fieschi (c. 1232–1303) was a Genoese nobleman of the counts of Lavagna, a son of Tedisio Fieschi and Simona della Volta and a brother of Pope Adrian V. He married Chiara, and through his daughter Eleonora's marriage in 1275 to Bernabò Doria he tied the Guelph Fieschi house to the Ghibelline Doria dynasty.

In 1303, at Sarzana, he made his will, naming Eleonora his heiress; he was later buried in Genoa at San Francesco di Castelletto.
