What Is the Twins Days Festival?

The Twins Days Festival is the largest annual gathering of twins and multiples in the world, held in Twinsburg, Ohio. It takes place every year during the first full weekend of August. The next edition runs August 7–9, 2026, with future dates already set: August 6–8, 2027, and August 4–6, 2028.

Where and when it happens

The "first full weekend" pattern makes the event predictable year to year, which matters if you're planning travel or requesting time off.

Who it's for

The festival is built around twins and multiples — twins, triplets, and larger sets — along with their families and visitors. It functions as both a celebration and a large-scale meetup, giving attendees a rare chance to be in a crowd where being a twin is the norm rather than the exception.

Why it exists

Twinsburg has hosted this gathering for decades, and its scale is the point: it's described as the world's largest annual gathering of twins and multiples. For attendees, the appeal is usually a mix of community, shared experience, and the novelty of a town temporarily dominated by pairs and sets.
