July 5-9, 2023

Event Details

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.

The 2023 Annual Gathering is dropping anchor on the East Coast, and we're going to make a real splash on the Harbor! It's always been a favorite way to socialize, learn, and explore, but this year we're benefiting from a wealth of expertise in the D.C. area to provide a first-class programming experience. Watch for a reimagined feel to go along with AG staples such as Spark!, tours, games, and tournaments.
