Why is the Buckeye associated with Ohio and with OSU?
Ohio is known as the “Buckeye State,” the Ohio Buckeye is the official state tree, and Ohioans in general, but especially those associated with Ohio State University, are known as “buckeyes.” The origin of this nickname, which dates from early pioneer days, is not completely known. Ohio may have become known as the Buckeye State simply because many large, economically important buckeye trees grew in the Ohio region at that time.
