A Provincial Superior is a major superior of a religious institute acting under the institute's Superior General and exercising a general supervision over all the members of that institute in a territorial division of the order called a province—similar to but not to be confused with an ecclesiastical province made up of particular churches or dioceses under the supervision of a Metropolitan Bishop. The division of a religious institute into provinces is generally along geographical lines, and may consist of one or more countries, or of only a part of a country. There may be, however, one or more houses of one province situated within the physical territory of another since the jurisdiction over the individual religious is personal rather than territorial. The title of the office is often abbreviated to Provincial.
Among the friars and Third Order Religious Sisters of the Augustinian, Carmelite and Dominican orders, the title "Prior Provincial" or Prioress Provincial is generally used. The Friars Minor, in contrast, use the title "Minister Provincial", in line with their emphasis on living as brothers to one another.
The old orders had no provincial superiors; even when the monasteries were united to form congregations, the arch-abbot of each congregation was in the position of a superior general whose powers were limited to particular cases, almost like the powers of a metropolitan archbishop over the dioceses of his suffragans. Provincial superiors are found in the institutes of more recent formation, which began with the mendicant orders. The Holy See hesitated for a long time before allowing the division of congregations with simple vows, especially congregations of women, into different provinces as a regular institution, and some congregations have no such division.
