Battle of the Atlantic can refer to either of two naval campaigns, depending on context:

• World War I - First Battle of the Atlantic
• World War II - Second Battle of the Atlantic

A Third Battle of the Atlantic was envisioned to be part of any Third World War that arose out of the Cold War. Trans-Atlantic convoys would have to be protected from the Soviet Navy and as a result, the Royal Navy and the U.S. Navy developed anti-submarine warfare capabilities. This affected much of the two navies' operational planning.
