Ohio State Flag - Official Design, Symbolism, and History #1370876 (License: Personal Use)

Ohio’s flag, adopted in 1902, is the only U.S. state flag that is not rectangular; its swallowtail shape resembles a pennant. It features three red and two white horizontal stripes, a blue triangular canton with 17 white stars (representing Ohio as the 17th state), and a large red disc encircled by white-symbolizing the state’s hills and fields, as well as its nickname, “The Buckeye State.” The flag was designed by John Eisenmann and remains a proud emblem of Ohioan identity.
