The Connecticut class of pre-dreadnought battleships were the penultimate class of the type built for the United States Navy. The class comprised six ships: Connecticut, Louisiana, Vermont, Kansas, Minnesota, and New Hampshire, which were built between 1903 and 1908. The ships were armed with a mixed offensive battery of 12-inch (305 mm), 8-inch (203 mm), and 7-inch (178 mm) guns. This arrangement was rendered obsolete by the advent of all-big-gun battleships like the British HMS Dreadnought, which was completed before most of the Connecticuts entered service.

Pre-dreadnought battleships were sea-going battleships built from the mid- to late- 1880s to the early 1900s. Their designs were conceived before the appearance of HMS Dreadnought in 1906 and their classification as "pre-dreadnought" is retrospectively applied. In their day, they were simply known as "battleships" or else more rank-specific terms such as "first-class battleship" and so forth. The pre-dreadnought battleships were the pre-eminent warships of their time and replaced the ironclad battleships of the 1870s and 1880s.
