USS Columbia (SSN-771), is the 60th flight II Improved Los Angeles-class attack submarine, and is the eighth vessel of the United States Navy to bear that name. The earlier Columbia's were given their names for differing reasons; SSN-771 was specifically named in honor of Columbia, South Carolina, Columbia, Missouri, and Columbia, Illinois.

The contract to build Columbia was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut on 14 December 1988 and her keel was laid down on 21 April 1993. She was the 33rd Los Angeles class built by EB, and was launched on 24 September 1994 with the slide down a 1300-foot wooden ramp, the last American submarine to do so, giving her the title of "The Last Slider."

Columbia was sponsored by Hillary Clinton, and commissioned on 9 October 1995, with Commander Dale Govan in command.

Another U.S. sub sharing the same name[edit]

Although no decommissioning date has been announced for this Columbia, it has been announced that the lead ship of the Ohio-class replacement ballistic missile submarines, will also be named Columbia (SSBN-826), though named for District of Columbia, and is scheduled to begin construction in 2021 and enter service in 2031.
