USS Ohio (BB-12), a Maine-class battleship pre-dreadnought battleship, was the third ship both of her class and 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.

Ohio was 393 feet 11 inches (120.07 m) long overall and had a beam of 72 ft 3 in (22.02 m) and a draft of 24 ft 4 in (7.42 m). She displaced 12,723 long tons (12,927 t) as designed and up to 13,700 long tons (13,900 t) at full load. The ship was powered by two-shaft triple-expansion steam engines rated at 16,000 indicated horsepower (12,000 kW) and twelve coal-fired Thornycroft boilers, generating a top speed of 18 knots (33 km/h; 21 mph). As built, she was fitted with heavy military masts, but these were quickly replaced by cage masts in 1909. She had a crew of 561 officers and enlisted men, which increased to 779–813.
