About American Mensa

The organization
for smart people like you

With more than 57,000 members, American Mensa is the largest national Mensa operating under the auspices of Mensa International, Ltd. There are currently more than 100,000 members worldwide, and an estimated six million Americans are eligible for Mensa membership.

Members of American Mensa range in age from 2 to 102. They include engineers, homemakers, teachers, actors, athletes, students and CEOs, and they share only one trait — high intelligence. To qualify for Mensa, they scored in the top 2 percent of the general population on an accepted standardized intelligence test.

As a member, you have the opportunity to meet other smart people at local, regional and national levels. You can attend entertaining, intellectually stimulating events and exchange ideas with others through a variety of publications and our online Community. You can also work to help others in your community by volunteering for community-oriented activities and working with the Mensa Foundation. And you can take advantage of our variety of member benefits and services.
