Lamberto II da Polenta
Lamberto II da Polenta (died 1347) was shortly lord of Ravenna and Cervia from 1346 until his death.
He was the son of Ostasio I da Polenta. In 1346 he inherited the family lordships together with his brothers Bernardino I and Lamberto II. The former, however, had both Pandolfo and Lamberto imprisoned in Cervia after one year, where they died of starvation.
