The First Cruiser Squadron was a Royal Navy squadron of cruisers that saw service as part of the Grand Fleet during World War I, then later as part of the Mediterranean during the Interwar period and World War II. It was first established in 1904 and existed until 1952.

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.
