USS Montana (ACR-13/CA-13), also referred to as "Armored Cruiser No. 13", later renamed Missoula and reclassified CA-13, was a Tennessee-class armored cruiser of the United States Navy. She was built by the Newport News Drydock & Shipbuilding Co.; her keel was laid down in April 1905, she was launched in December 1906, and she was commissioned in July 1908. The final class of armored cruisers to be built for the US Navy, Montana and her sisters were armed with a main battery of four 10-inch (254 mm) guns, and they were capable of a top speed of 22 knots.

The Tennessee-class cruisers were four armored cruisers built for the United States Navy between 1903 and 1906. Their main armament of four 10-inch (254 mm) guns in twin turrets was the heaviest carried by any American armored cruiser. Their armor was thinner than that of the six Pennsylvanias which immediately preceded them, a controversial but inevitable decision due to newly imposed congressional restraints on tonnage for armored cruisers and the need for them to be able to steam at 22 knots. However, the fact their armor covered a wider area of the ship than in the Pennsylvanias and their increased firepower caused them to be seen by the Navy as an improvement.
