International Islamic Relief Organization

The International Islamic Relief Organization (IIRO; Arabic: هيئة الإغاثة الإسلامية العالمية‎‎), also known as the International Islamic Relief Organization of Saudi Arabia (IIROSA), is a charity based in Saudi Arabia founded by the Muslim World League in 1978. It is a full member of The Conference of NGOs, where it serves on the board. The IIRO is included in a list of some of the UNHCR's major NGO partners and has been involved in many joint programmes with UN Agencies and intergovernmental (such as the World Health Organization) and non-governmental organisations. It has enjoyed consultative status on the United Nations Economic and Social Council since 1995. It was the first Islamic NGO to gain observer status with the International Organisation for Migration (IOM). It is also a member of the International Humanitarian City based in Dubai, UAE.

Following the 9/11 terror attacks, it was alleged that one of Osama bin-Laden's brothers-in-law had utilised the IIRO Philippines and Indonesian Branches to work with terrorist organizations worldwide, and that a brother of Al-Qaeda official Ayman al Zawahiri working for the IIRO in Albania had brought a number of members of the terror group Egyptian Islamic Jihad to work for IIRO in that European country. IIRO denies any wrongdoing.

IIRO is an affiliate of the Muslim World League (MWL). A Saudi royal decree issued on January 29, 1979 approved the decision of MWL to form IIROSA made in 1978.

It is a member of the International Islamic Council for Da'wah and Relief (IICDR), has observer status at Organisation of the Islamic Cooperation, consultative status at United Nations Economic and Social Council (ECOSOC) and links to Islamic Educational, Scientific and Cultural Organization (ISESCO) among many others.
