Catholic Relief Services (CRS) is the international humanitarian agency of the Catholic community in the United States. Founded in 1943 by the Bishops of the United States, the agency assists 130 million people in more than 110 countries and territories in Africa, Asia, Latin America, the Middle East, and Eastern Europe.

A member of Caritas International, the worldwide network of Catholic humanitarian agencies, CRS provides relief in emergencies and helps people in the developing world break the cycle of poverty through community-based, sustainable development initiatives as well as Peacebuilding. Assistance is based solely on need, not race, creed, or nationality. Catholic Relief Services is headquartered in the Posner Building in Baltimore, Maryland while operating numerous field offices on five continents. CRS has approximately 5,000 employees around the world. The agency is governed by a board of directors consisting of 13 clergy (most of them bishops) and 10 laypeople.
