USS Oregon (BB-3) was a pre-dreadnought Indiana-class battleship of the United States Navy. Her construction was authorized on 30 June 1890, was awarded to Union Iron Works of San Francisco and launched on 26 October 1893, sponsored by Miss Daisy Ainsworth (daughter of Oregon steamboat magnate John C. Ainsworth), and commissioned on 15 July 1896.
While a voyage around South America to the East Coast in March 1898 in preparation for war with Spain, she made a journey of 14,000 nautical miles (26,000 km; 16,000 mi) - a remarkable achievement at the time. The journey popularized the ship with the American public and demonstrated the need for a shorter route, which led to a construction of the Panama Canal. She took part in the Battle of Santiago de Cuba, where she and the cruiser Brooklyn were the only ships fast enough to chase down the Spanish cruiser Cristóbal Colón, forcing its surrender and received the nickname "Bulldog of the Navy".
Oregon was recommissioned in August 1911 but after the United States joined World War I in 1917, Oregon acted as one of the escorts for transport ships during the Siberian Intervention. In October 1919, she was decommissioned for the final time.
In June 1925 she was loaned to the State of Oregon, who used her as a floating monument and museum in Portland, but due to the outbreak of World War II it was decided that the scrap value of the ship was more important than her historical value, so she was sold and, after a decade, scrapped.
