The Northern Patrol, also known as Cruiser Force B and the Northern Patrol Force, was an operation of the British Royal Navy during the First World War and Second World War. The Patrol was part of the British "distant" Blockade of Germany (1914–1919) and the Blockade of Germany (1939–1945). Its main task was to prevent trade to and from Germany by checking merchant ships and their cargoes. It was also to stop German warships, raiders and other German naval ships from leaving the North Sea for the Atlantic Ocean or entering the North Sea from the Atlantic, protect Shetland against invasion and to gather intelligence from intercepted neutral ships.^[1]

The Northern Patrol operated under the command of the Grand Fleet during the First World War. At first, Edgar-class cruisers were used but these were not built for the seas around Scotland in winter and were replaced by civilian ships pressed into service as Armed Merchant Cruisers.

In the Second World War the Northern Patrol was commanded by the Home Fleet in the. Perhaps the Northern Patrol's most famous action was the loss of the armed merchant cruiser On 23 November 1939. Captain Edward Kennedy RN, commander of the ANC HMS Rawalpindi decided to fight the 11-inch gun German capital ships Scharnhorst and Gneisenau, rather than surrender as demanded. The crew of Rawalpindi managed to inflict splinter damage on Scharnhorst during a short engagement, before being sunk only a few survivors being rescued by the Germans.
