The Priestly Fraternity of Saint Peter (Latin: Fraternitas Sacerdotalis Sancti Petri; FSSP) is a traditionalist Catholic society of apostolic life for priests and seminarians. It is in communion with the Holy See. It was founded in 1988 by 12 former members of the Society of Saint Pius X (SSPX) who left following the Écône consecrations, which resulted in the SSPX bishops being excommunicated by the Holy See.

Headquartered in Switzerland, the society maintains two international seminaries: the International Seminary of St. Peter in Wigratzbad-Opfenbach, Bavaria, Germany, and Our Lady of Guadalupe Seminary in Denton, Nebraska, United States. The society is officially recognized by the Holy See and has 368 priests who celebrate the Tridentine Mass in locations in 147 worldwide dioceses.
