Saltaro was a Sardinian nobleman during the Middle Ages, the son of Constantine I of Logudoro. His mother is unknown but may have been named Marcusa. Whether or not he is the same person as "Saltaro de Gunale", a pretender to the throne of Logudoro in 1127 during the reign of Gonario II, is also uncertain.
While still a young man, Saltaro took part in the Pisan expedition against the Moors of the Balearic Islands in 1114 - 1115. He was renowned for his handling of the ships and his participation brought honour to his father.
