The John Paul II Pontifical Theological Institute for Marriage and Family Sciences is a Catholic pontifical institute of theological studies on marriage and family with affiliated campuses around the world.

In 1981, Pope John Paul II founded the Pontifical Institute for Studies on Marriage and Family in the Apostolic Constitution Magnum Matrimonii Sacramentum, as part of the effort to develop study on the themes around the marriage and family, as well as Catholic theology on the body.

[1] In 2017, Pope Francis issued a motu proprio Summa familiae cura ("By the greatest concern for the family"), replacing the institute with the John Paul II Pontifical Theological Institute for Marriage and Family Sciences, with a new constitution and mission.

[1] The institute confers degrees including Doctor, Licentiate, and Diploma of Science in Marriage and Family under its own authority.

[1] The institute's governance is, as a pontifical school, largely made up of Catholic prelates.
