The Order of Knights of the Hospital of Saint John of Jerusalem (; ), also known as the Order of Saint John, Order of Hospitallers, Knights Hospitaller, Knights Hospitalier or Hospitallers, was a medieval and early modern Catholic military order.

All of them were subject to the Grand Master, appointed for life, who oversaw both the order's military efforts in the East and their financial holdings in the West. The Grand Master exercised his authority via the visitors-general of the order, who were knights specially appointed by the Grand Master and convent of Jerusalem to visit the different provinces, correct malpractices, introduce new regulations, and resolve important disputes. The visitors-general had the power to remove knights from office and to suspend the Master of the province concerned.
