The Royal Artillery Memorial is a First World War memorial located on Hyde Park Corner in London, England. Designed by Charles Sargeant Jagger, with architectural work by Lionel Pearson, and unveiled in 1925, the memorial commemorates the 49,076 soldiers from the Royal Artillery killed in the First World War. The static nature of the conflict, particularly on the Western Front, meant that artillery played a major role in the war, though physical reminders of the fighting were often avoided in the years after the war. The Royal Artillery War Commemoration Fund (RAWCF) was formed in 1918 to preside over the regiment's commemorations, aware of some dissatisfaction with memorials to previous wars. The RAWCF approached several eminent architects but its insistence on a visual representation of artillery meant that none was able to produce a satisfactory design. Thus they approached Jagger, himself an ex-soldier who had been wounded in the war. Jagger produced a design which was accepted in 1922, though he modified it several times before construction.

World War I is remembered and commemorated by various war memorials, including civic memorials, larger national monuments, war cemeteries, private memorials and a range of utilitarian designs such as halls and parks, dedicated to remembering those involved in the conflict. Huge numbers of memorials were built in the 1920s and 1930s, with around 176,000 erected in France alone. This was a new social phenomenon and marked a major cultural shift in how nations commemorated conflicts. Interest in World War I and its memorials faded after World War II, and did not increase again until the 1980s and 1990s, which saw the renovation of many existing memorials and the opening of new sites. Visitor numbers at many memorials increased significantly, while major national and civic memorials continue to be used for annual ceremonies remembering the war.
