Galvano da Levanto or Galvanus de Levanto (fl. c. 1300) was a Genoese physician and writer. Devoutly religious, he may have joined the Third Order of Saint Francis. Having suffered medical and financial problems, he sought the patronage of King Philip IV of France and later Pope Boniface VIII and the Curia romana. He wrote prolifically on medical and theological topics, but his most famous work today is his crusade treatise.
