Marino Faliero was the fifty-fifth Doge of Venice. He was sometimes referred to simply as Marin Falier. He was appointed on 11 September 1354. The only Doge of the first seventy-six not to have his portrait displayed in the Sala del Maggior Consiglio (Hall of the Major Council) in Palazzo Ducale (Doge's Palace) on St Mark's Square.

Attempted a failed coup d'etat in 1355, at the time being Doge himself, but with the intention of declaring himself Prince. His actions are mostly contributed to a combination of a strong hatred for nobility and his senility (he was in his seventies at the time). He pleaded guilty to all charges and was executed and his body mutilated. The ten additional ringleaders were hung on display from the Palazzo Ducale.
