The Pontifical Lombard Seminary of Saints Ambrose and Charles in Urbe (Italian: Pontificio seminario lombardo dei santi Ambrogio e Carlo in Urbe) is an ecclesiastical institution that serves as a residence for and trains diocesan priests who have been sent to Rome by their bishop to pursue an advanced degree or follow a specialized course of study at one of the pontifical universities there.
The seminary is subject to the authority of the Lombard Episcopal Conference and as a Roman ecclesiastical institute it also has a particular dependence on the Holy See. While many of the students originate in the dioceses of Lombardy, the seminary accepts priests from other dioceses, both Italian and not.
