A suffragan bishop is a type of bishop in some Christian denominations.
In the Catholic Church, a suffragan bishop leads a diocese within an ecclesiastical province other than the principal diocese, the metropolitan archdiocese; the diocese led by the suffragan is called a suffragan diocese.
In the Anglican Communion, a suffragan bishop is a bishop who is subordinate to a metropolitan bishop or diocesan bishop (bishop ordinary) and so is not normally jurisdictional in their role. Suffragan bishops may be charged by a metropolitan to oversee a suffragan diocese and may be assigned to areas which do not have a cathedral.
