Ormanno di Rinaldo degli Albizzi (7 March 1398, Florence - 1457 or after) was an Italian (Republic of Florence) ambassador and military, firstborn of Rinaldo degli Albizzi and his wife Alessandra de' Ricco.

After the restoration of the Medici rulership, Rinaldo degli Albizi was exiled.

Two years later Ormanno was declared a rebel and exiled too, and he fled to Trapani.

[1] He spent a few years at the Gonzaga court in Mantua before moving to Gaeta with King Alfonso V of Aragon.

He sent ambassadors to Florence in 1455 and 1457 with the intention to obtain permission to return, but Cosimo de' Medici was adamant in confirming his exile.
