The Largest Yearly Confab of Mensans Anywhere
The American Mensa Annual Gathering started as a small, two-day meet-and-greet at the New York Belmont in 1963. The event now spans five days and features a sprawl of talks, games, and entertainment unlike any other.
We have a fantastic party in the works for Annual Gathering 2025, July 2 - 6! Chicago is a revolution of creativity, music, food, art, and spirit … and we get to enjoy it all week! Come see all your friends and perhaps make a few new ones. Trust us, this AG is going to be lit!
