The pursuit of Goeben and Breslau was a naval action that occurred in the Mediterranean Sea at the outbreak of the First World War when elements of the British Mediterranean Fleet attempted to intercept the German Mittelmeerdivision consisting of the battlecruiser SMS Goeben and the light cruiser SMS Breslau. The German ships evaded the British fleet and passed through the Dardanelles to reach Constantinople, where they were eventually handed over to the Ottoman Empire. Renamed Yavuz Sultan Selim and Midilli, the former Goeben and Breslau were ordered by their German commander to attack Russian positions, in doing so bringing the Ottoman Empire into the war on the side of the Central Powers.

The British Mediterranean Fleet, also known as the Mediterranean Station, was a formation of the Royal Navy. The Fleet was one of the most prestigious commands in the navy for the majority of its history, defending the vital sea link between the United Kingdom and the majority of the British Empire in the Eastern Hemisphere. The first Commander-in-Chief for the Mediterranean Fleet was the appointment of General at Sea Robert Blake in September 1654. The Fleet was in existence until 1967.
