Alvica Gradenigo

Alvica Gradenigo was a Venetian noblewoman, a granddaughter of Doge Pietro Gradenigo and the daughter of Nicolo Gradenigo; she is named in her grandfather's will of 1309. By 1335 she had married Marino Falier as his second wife, becoming dogaressa when he took office in 1354.

After Falier was executed for his coup attempt in 1355, the Council of Ten cleared her of complicity and returned her dowry of 4000 lire. During a long widowhood she traded and lent money, dying in 1387 or 1388 as one of the richest women in Venice.
