In Christianity, an archbishop (, via Latin "archiepiscopus", from Greek , from -, "chief", and , "bishop") is a bishop of higher rank or office. In some cases, like the Lutheran Church of Sweden, it is the denomination leader title. Like popes, patriarchs, metropolitans, cardinal bishops, diocesan bishops, and suffragan bishops, archbishops are in the highest of the three traditional orders of bishops, priests, also called presbyters, and deacons. An archbishop may be granted the title, or ordained as chief pastor of a metropolitan see or another episcopal see to which the title of archbishop is attached. 

Episcopal sees are generally arranged in groups in which the bishop who is the ordinary of one of them has certain powers and duties of oversight over the other sees. He is known as the metropolitan archbishop of that see. In the Roman Catholic Church, canon 436 of the Code of Canon Law indicates what these powers and duties are for a Latin Rite metropolitan archbishop, while those of the head of an autonomous ("sui iuris") Eastern Catholic Church are indicated in canon 157 of the Code of Canons of the Eastern Churches. 

As well as the much more numerous metropolitan sees, there are 77 Roman Catholic sees that have archiepiscopal rank. In some cases, such a see is the only one in a country, such as Luxembourg or Monaco, too small to be divided into several dioceses so as to form an ecclesiastical province. In others, the title of archdiocese is for historical reasons attributed to a see that was once of greater importance.
