The world's largest high-IQ society, Mensa exists to identify and foster human intelligence for the benefit of humanity; to encourage research into the nature, characteristics, and uses of intelligence; and to provide a stimulating intellectual and social environment for its more than 130,000 members worldwide. American Mensa is largest national chapter of Mensa International. We provide a home for the intellectually curious to exchange ideas, engage in debate, and connect with those who share a thirst for information.

Our philanthropic arm, the Mensa Education and Research Foundation, shows its commitment to the pursuit of excellence in human intelligence globally through international scholarship and awards programs, educational outreach and events, and research publications.
