The International Institute of Islamic Thought (IIIT) is the premier international organization focusing on providing a platform for the unique perspective of Muslim thinkers, scholars and practitioners in the humanities and social sciences. For 40 years, IIIT has been a voice for moderation, diversity and modernity in Islamic thought, with an emphasis on concepts such as co-existence and building the capacity of communities to address their common global and local challenges. Today, IIIT is the voice of the Muslim intellectual tradition in the west, and a champion for scholarship, knowledge and learning in Muslim societies across the world.

IIIT was established in 1981 as a U.S. non-profit 501(c)(3) non-denominational organization. Its headquarters are in Herndon, Virginia, in the suburbs of Washington, D.C.
