USS Louisiana (BB-19) was a Connecticut-class battleship of the United States Navy. She was the second member of the class of six pre-dreadnought battleships, and the third ship to carry her name. Louisiana was laid down in February 1903, launched in August 1904, and commissioned in June 1906. She was a 16,000-long-ton (16,000 t) battleship capable of 19 knots (35 km/h; 22 mph). Her main armament consisted of four 12-inch (305 mm) guns supported by a mixed secondary battery of 7 in (178 mm) and 8 in (203 mm) guns.

Louisiana primarily operated along the east coast of the United States and in the Caribbean during her career. In 1908–09, she took part in the world cruise of the Great White Fleet. A pair of trips to European waters took place in 1910 and 1911. From 1913, she began to become involved in the Mexican Revolution, as the US Navy began to send ships to protect American interests in the country. This activity culminated in the US occupation of Veracruz in April 1914. During World War I, Louisiana was employed as a training ship before serving as a convoy escort in late 1918. After the war ended that year, she was used to ferry American soldiers back from France. With this work completed, she was decommissioned in October 1920 and broken up for scrap at the Philadelphia Navy Yard in 1923.

Louisiana was 456.3 ft (139.1 m) long overall and had a beam of 76.9 ft (23.4 m) and a draft of 24.5 ft (7.5 m). She displaced 16,000 long tons (16,000 t) as designed and up to 17,666 long tons (17,949 t) at full load. The ship was powered by two-shaft triple-expansion steam engines rated at 16,500 indicated horsepower (12,300 kW) and twelve coal-fired Babcock & Wilcox 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 lattice masts in 1909. She had a crew of 827 officers and enlisted men, though this increased to 881 and later to 896.
