The Unique Ohio State Flag: America’s Only Non-Rectangular State Flag

Most state flags blend into a familiar format—rectangular, safe, expected. But Ohio? Ohio took one look at tradition and carved out its own shape. Literally. With a bold swallowtail design and symbolism stitched with pride, the Ohio state flag doesn’t just wave—it declares.

The Flag That Broke the Mold

In 1902, architect John Eisenmann wasn’t just tasked with designing a flag—he was asked to represent Ohio at the Pan-American Exposition in Buffalo. What he delivered was more than fabric; it was a statement. Eisenmann broke with convention and designed the only non-rectangular state flag in the U.S., borrowing from nautical pennants and military banners.

What’s the result? A flag that moves like no other. That swallowtail isn’t just stylish—it’s a nod to Ohio’s bold independence and a tribute to its role in American progress.

What Do the Symbols Mean?

The Ohio state flag is rich with meaning, every detail echoing the state’s geography, legacy, and place in the Union:

• Red, White, and Blue: A proud salute to America and Ohio’s patriotic roots.
• Blue Triangle: Representing Ohio’s rolling hills and river valleys.
• 17 Stars: Thirteen for the original colonies, four for Ohio’s entry as the 17th state.
• Red Circle: A stylized "O" for Ohio and a nod to the buckeye tree.

“Ohio’s flag tells a story in motion—of pioneers, inventors, and the spirit of a state that never sits still.”

Why a Swallowtail?

Ohio’s flag isn’t just different for difference’s sake. The swallowtail design links to military history and movement—something Ohio has always been a part of. From the Wright brothers to steelworkers, from astronauts to artists, Ohioans have propelled the nation forward. The flag mirrors that forward motion with every ripple in the wind.

Modern Meaning and Where You’ll Find It

Walk through a Buckeye State neighborhood or tailgate on game day, and you’ll find the flag flying proudly. It’s not just for government buildings anymore—it’s in backyards, classrooms, and stadiums. Ohioans don’t just salute their flag—they wear it, wave it, and live it.

The flag has become a modern emblem of:

• Unity across regions—from Cleveland to Cincinnati, Columbus to Athens.
• Innovation and legacy—home to presidents, inventors, and pioneers.
• Resilience—weathering economic shifts and emerging stronger.
