Master general or Master-general can refer to:
- the Superior general of certain orders and congregations, such as
- certain secular titles and offices, such as Master-General of the Ordnance
The title was also sometimes used interchangeably with the other title of Grand Master, especially when referring to chivalric orders in the Middle Ages. In some chivalric orders, for example the Order of Saint Lazarus, this title was used by the Boigny Knights under the protection of the French monarchy so as to bypass a number of Papal Bulls which were intended to abolish the Order itself. Roman historians Ammianus and Zozimus record that the Master General Vietor led the center column of three columns of infantry to push the Roman march through the country and into battle.
Even today, the Order of Saint Lazarus, albeit fragmented into a number of varying factions and obediences, one of the Lazarite Groupings headquartered in London with Grand Priories and Commanderies in various countries, is led by a Master-general Fra John Baron von Hoff GCLJ GCMLJ who was unanimously appointed to the title by the Knights in Council of the United Grand Priories.
