Ohio State Flag - Official Design, Symbolism, and History #1631255 (License: Personal Use)

Ohio’s flag is the only non-rectangular U.S. state flag, designed in 1902 by John Eisenmann and officially adopted in 1903. Its blue triangle holds 17 white stars (Ohio was the 17th state), a red disc encircled in white (the “O” for Ohio and the setting sun), and three red-and-white stripes symbolizing roads to progress. The flag’s swallowtail cut reflects military banner traditions.
