Mother Teresa Institute (MTI)  is an outgrowth of the work and activities of The Mother Teresa Center, a non-profit organization established and directed by the religious family founded by Mother Teresa of Calcutta, The Missionaries of Charity.

The aim of the MTI is to preserve, protect, promote, and develop the authentic legacy of Saint Teresa of Calcutta to the Church and to the world. The MTI will provide resources to students, scholars and researchers who are interested in Mother Teresa, her life, charism and message, giving them the opportunity to study in depth one of the great saints of modern times and a humanitarian figure who made an enormous difference to the welfare of the poorest of the poor and had broad influence in the Church and the world.
