Lamberto II da Polenta
Lamberto II da Polenta (died 1347) was a son of Ostasio I da Polenta, lord of Ravenna and Cervia. When Ostasio died in 1346, Lamberto inherited the lordships together with his brothers Bernardino I and Pandolfo.
Bernardino I soon made himself sole ruler and shut Lamberto and Pandolfo up at Cervia, where the two brothers were starved to death in 1347.
