The Royal Aal al-Bayt Institute for Islamic Thought is an international Islamic non-governmental, independent institute in Amman, Jordan. It is affiliated with the Royal Islamic Strategic Studies Centre.
The late King Hussein Bin Talal established the Institute in 1980, and entrusted it to Prince Prince Hassan bin Talal. It passed on to Crown Prince Prince Hamzah bin Al Hussein on August 8, 1999 and then to Prince Ghazi bin Muhammad, who is the Chair of the Board of Trustees.
Fellows of the Institute attend a conference every 2–3 years. The last one was held in September 2010, under the title "Islam and the Environment".
