The First Battlecruiser Squadron was a Royal Navy squadron of battlecruisers that saw service as part of the Grand Fleet during the First World War. It was created in 1909 as the First Cruiser Squadron and was renamed in 1913 to First Battle Cruiser Squadron. It participated in the battles of Heligoland Bight, Dogger Bank and the Battle of Jutland. After the end of the war it became the sole Battlecruiser Squadron.

The Battle of Dogger Bank was a naval engagement during the First World War that took place on 24 January 1915 near the Dogger Bank in the North Sea, between squadrons of the British Grand Fleet and the Kaiserliche Marine. The British had intercepted and decoded German wireless transmissions, gaining advance knowledge that a German raiding squadron was heading for the Dogger Bank and ships of the Grand Fleet sailed to intercept the raiders.
