The Battle of Hampton Roads, also referred to as the Battle of the Monitor and Merrimack (rebuilt and renamed as the CSS Virginia) or the Battle of Ironclads, was a naval battle during the American Civil War. It was fought over two days, March 8–9, 1862, in Hampton Roads, a roadstead in Virginia where the Elizabeth and Nansemond rivers meet the James River just before it enters Chesapeake Bay adjacent to the city of Norfolk. The battle was a part of the effort of the Confederacy to break the Union blockade, which had cut off Virginia's largest cities and major industrial centers, Norfolk and Richmond, from international trade.

During the night, however, the ironclad Monitor had arrived and had taken a position to defend Minnesota. When Virginia approached, Monitor intercepted her. The two ironclads fought for about three hours, with neither being able to inflict significant damage on the other. The duel ended indecisively, Virginia returning to her home at the Gosport Navy Yard for repairs and strengthening, and Monitor to her station defending Minnesota. The ships did not fight again, and the blockade remained in place. The battle received worldwide attention, and it had immediate effects on navies around the world. The preeminent naval powers, Great Britain and France, halted further construction of wooden-hulled ships, and others followed suit.
