HMS Collingwood was a St Vincent-class dreadnought battleship built for the Royal Navy in the first decade of the 20th century. She spent her whole career assigned to the Home and Grand Fleets and often served as a flagship. Prince Albert spent several years aboard the ship before and during World War I. At the Battle of Jutland in May 1916, Collingwood was in the middle of the battleline and lightly damaged a German battlecruiser. Other than that battle, and the inconclusive action of 19 August, her service during the war generally consisted of routine patrols and training in the North Sea. The ship was deemed obsolete after the war; she was reduced to reserve and used as a training ship before being sold for scrap in 1922.

The St Vincent-class battleships were a group of three dreadnought battleships built for the Royal Navy in the first decade of the 20th century. The sister ships spent their entire careers assigned to the Home and Grand Fleets. Aside from participating in the Battle of Jutland in May 1916 and the inconclusive action of 19 August several months later, their service during the First World War generally consisted of routine patrols and training in the North Sea. Vanguard was destroyed in 1917 by a magazine explosion with the near total loss of her crew. The remaining pair were obsolete by the end of the war in 1918, and spent their remaining time either in reserve or as training ships before being sold for scrap in the early 1920s.
