Maryknoll is a name shared by three organizations (two religious institutes and one lay ministry) that are part of the Roman Catholic Church: Maryknoll Fathers and Brothers (Catholic Foreign Mission Society of America; Maryknoll Society), Maryknoll Sisters (Maryknoll Sisters of St. Dominic), and Maryknoll Lay Missioners. The organizations are independent entities with shared history that work closely together in the joint focus of the overseas mission activity of the Catholic Church particularly in East Asia, China, Japan, Korea, Latin America and Africa. The organizations officially began in 1911, founded by Thomas Frederick Price, James Anthony Walsh, and Mary Joseph Rogers. The name Maryknoll comes from the hill outside the Village of Ossining, Westchester County, New York, which houses the headquarters of all three. Members of the societies are usually called Maryknollers.
Maryknollers are sometimes known as the "Marines of the Catholic Church" for their reputation of moving into rough areas, living side-by-side with the indigenous peoples and learning the language. Maryknollers focus on "combating poverty, providing healthcare, building communities and advancing peace and social justice" in the countries they serve and have built numerous orphanages, primary schools and secondary schools. Because of the way in which Maryknollers have especially engaged in social justice, Maryknoll is also sometimes seen as a movement that represents missionary service concerned with positive action for indigenous people. In the mid-20th century, this movement came to be associated with Liberation theology. The Christophers and The Maryknoll Affiliates are both associated with the Maryknoll Movement. Maryknoll is also the current name of the semi-monthly magazine which the Maryknoll Fathers & Brothers publish.
