汉普顿锚地海战（又称：汉普顿锚地之战，英语：Battle of Hampton Roads，英语也称：Battle of the Monitor and Merrimack或Merrimac）是美国内战的一次海战。从海军发展的观点来看，这次海战是美国南北战争最著名和最为重要的海战，是历史上第一次以钢制成装甲的铁甲舰之间对决，邦联的CSS Virginia 和联邦的浅水重炮舰USS Monitor于维吉尼亚附近的汉普顿锚地从1862年3月8至9日进行的战斗。北方联邦的封锁切断了弗吉尼亚州最大城市诺福克和里士满的国际贸易。此次海战是南方邦联为打破封锁而努力的一部分。

The Battle of Hampton Roads, often referred to as either the Battle of the Monitor and Merrimack (or Virginia) or the Battle of Ironclads, was the most noted and arguably most important naval battle of the American Civil War from the standpoint of the development of navies. 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, Norfolk and Richmond, from international trade.
