Whether an animal, plant life, or mineral, these symbols represent Ohio and serve to unify Ohioans living in all corners of the Buckeye State.

From the roots of the buckeye tree to the flight path of the bright red cardinal, many of Ohio’s state symbols show a strong connection with nature. Ohio lawmakers have been designating state symbols since the early 19th century. Animals, plants, and even prehistoric fossils have made the list.
