Marino Sanuto (or Sanudo) Torsello (c. 1270–1343) was a Venetian statesman and geographer. He is best known for his lifelong attempts to revive the crusading spirit and movement; with this objective he wrote his Liber Secretorum Fidelium Crucis (Secrets for True Crusaders).

He is now sometimes referred to as Marino Sanuto the Elder to distinguish him from the later Venetian diarist of the same name.
