The Columbia-class cruisers were two protected cruisers constructed in 1890 and 1891 and used by the United States Navy.^[3] They were lightly gunned ships with only moderate armor that were built for the speed needed to overtake and destroy the fast ocean liners of the day as commerce raiders. However, the light armament and armor left these ships over-specialized and outclassed by ordinary similar sized protected cruisers that they might encounter. Also, the engines were expensive to operate and at full power the ships' range was greatly decreased. Due to the ongoing size and speed race in ocean liners, by 1907 they were outclassed in speed by the ill-fated Lusitania and the German liner Kronprinzessin Cecilie.^[4]

Columbia was authorized by an Act of Congress approved 30 June 1890, and Minneapolis was authorized by an Act approved 2 March 1891.^[5]
