The Missionaries of the Poor (Latin: Missionarii Pauperum) is a Roman Catholic monastic religious institute of Brothers and Sisters dedicated to "Joyful Service with Christ on the Cross" to serve the poorest of the poor. Its members use the nominal letters MOP (which is the acronym of its Latin name) after their names to indicate membership in the congregation. It was started in 1981 by The Very Reverend Father Richard Ho Lung, M.O.P. in Kingston, Jamaica and has now grown to over 550 Brothers and Sisters from 13 countries.
