Alderano Cybo-Malaspina (9 December 1552 in Massa – 16 November 1606 in Ferrara) was an Italian nobleman. He was marquess of Carrara, count of Ferentillo, first Duke of Ferentillo from 1603, Roman Patrician and Genoese Patrician, Patrician of Pisa and Florence, Patrician of Naples and Noble of Viterbo.
