Vettor Fausto or Vittore Fausto (1490–1546) was Venetian Renaissance humanist and naval architect. He was an expert in Greek and the classics. He worked as a copyist and a soldier in his youth. His studies led him to propose the construction of a quinquereme, a galley with five rowers per bench. He published original poetry in Greek, had a hand in the publication of the Complutensian Polyglot Bible and edited classical texts for publication, most notably the Aristotelis Mechanica, which he translated into Latin. In his later years he grew disillusioned with Venetian politics, even being accused of treason.
