USS Ohio (BB-12), a Maine-class pre-dreadnought battleship, was the third ship of her class and the third ship of the United States Navy to be named for the 17th state. She was laid down at the Union Iron Works shipyard in San Francisco in April 1899, was launched in May 1901, and was commissioned into the fleet in October 1904. She was armed with a main battery of four 12-inch (305 mm) guns and could steam at a top speed of 18 knots (33 km/h; 21 mph).

Ohio initially served in the Asiatic Fleet, from 1905 to 1907, when she returned to the United States. In December that year, she joined the Great White Fleet for its world cruise, which lasted until early 1909. She served with the Atlantic Fleet for the next four years conducting a peacetime training routine. In 1914, she was sent to Mexico to protect American interests in the country during the Mexican Revolution. She served as a training ship during America's involvement in World War I from 1917 to 1918. Thoroughly obsolete by that time, Ohio was decommissioned in July 1919, and was ultimately sold for scrap in March 1923 under the terms of the Washington Naval Treaty.
