USS Wisconsin (SSBN-827) will be the second Columbia-class ballistic missile submarine of the U.S. Navy. It is the third USN vessel to be named after the state of Wisconsin, the last of which was the Iowa-class battleship, USS Wisconsin (BB-64), decommissioned in 1991 and stricken from the Naval Vessel Register in 2006.

On October 28, 2020, it was announced by U.S. Secretary of the Navy Kenneth J. Braithwaite that the second named Columbia-class submarine would bear the name Wisconsin. This came from a bipartisan push from U.S. Senators Tammy Baldwin and Ron Johnson. Both senators cited Wisconsin's history of shipbuilding as a reason to name a new submarine after the state. Construction on the Wisconsin is scheduled to be procured in FY2024. The Columbia-class submarines are set to replace the Ohio-class ballistic missile submarine. The lead boat USS Columbia (SSBN-826) officially began construction on October 1, 2020 and is scheduled to enter service in 2031.
