A mission sui iuris, or in Latin missio sui iuris plural missions sui iuris; also spelled missions sui juris, also so-called as an freelancer mission, is a rare type of Roman Catholic missionary pseudo-diocesan jurisdiction, ranking below an apostolic prefecture and an apostolic vicariate, in an area with very few Catholics, often desolate or remote.
The clerical head is styled Ecclesiastical Superior; he can be acleric, titular or diocesan bishop, archbishop or even a cardinal, but if of episcopal style often resides elsewhere notably, in another diocese or the Vatican in chief of his primary business there.
It can either be exempt i.e. directly subjected to the Holy See, like Apostolic prefectures and Apostolic Vicariates, or suffragan of a Metropolitan Archbishop, hence component of his ecclesiastical province.
