The Missionary Oblates of Mary Immaculate (OMI) is a missionary religious congregation in the Catholic Church. It was founded on January 25, 1816, by Eugène de Mazenod, a French priest later recognized as a Catholic saint. The congregation was given recognition by Pope Leo XII on February 17, 1826. As of January 2020, the congregation was composed of 3,631 priests and lay brothers usually living in community. Their traditional salutation is Laudetur Iesus Christus ('Praised be Jesus Christ'), to which the response is Et Maria Immaculata ('And Mary Immaculate'). Members use the post-nominal letters "OMI".
As part of its mission to evangelize the "abandoned poor", OMI are known for their mission among the Indigenous peoples of Canada, and their historic administration of at least 57 schools within the Canadian Indian residential school system. Some of those schools have been associated with cases of child abuse by Oblate clergy and staff.: 399–452
