flag of Ohio
The Buckeye State
Admitted March 1, 1803

The Ohio flag is unlike any other U.S. flag due to its unique shape. It’s the only flag that isn’t a rectangle and is instead a swallow-tailed burgee.

It was designed by Cleveland architect John Eisenmann in 1901 for the Pan-American Exposition in New York, created to fly over the Ohio Building.

The flag was officially adopted May 9, 1902.


The Ohio flag is a broad pennant featuring three red and two white horizontal stripes.

A blue triangle extends from the hoist, its apex at the center of the middle red stripe.

Upon the blue triangle, a white circle surrounds an inset red disc. Seventeen white five-pointed stars surround.

John Eisenmann obtained a U.S. patent for his Ohio flag design and created detailed specification diagrams, simplified and recreated here.

The flag has an 8:13 proportion.

Many flag makers, rather than create the Ohio flag’s unique shape, print the Ohio flag on a rectangular field of white.
