"The British Grenadiers" is a traditional marching song of British and Commonwealth military units whose badge of identification features a grenade, the tune of which dates from the 17th century. It is the regimental quick march of the Royal Artillery, the Corps of Royal Engineers, the Honourable Artillery Company, the Grenadier Guards, and the Royal Regiment of Fusiliers. It is also an authorized march of the Royal Australian Artillery, the Royal Gibraltar Regiment, the Royal Regiment of Canadian Artillery, the Canadian Grenadier Guards, the Royal Regiment of Canada, and the Princess Louise Fusiliers. The standard orchestration for the military band was approved in 1762, when the Royal Artillery Band became recognized officially, and for all other "grenade" regiments in 1763, when the remaining unofficial bands gained official status.

A march, as a musical genre, is a piece of music with a strong regular rhythm which in origin was expressly written for marching to and most frequently performed by a military band. In mood, marches range from the moving death march in Wagner's Götterdämmerung to the brisk military marches of John Philip Sousa and the martial hymns of the late 19th century. Examples of the varied use of the march can be found in Beethoven's Eroica Symphony, in the Marches Militaires of Franz Schubert, in the Marche funèbre in Chopin's Sonata in B flat minor, the "Jäger March" in the Op. 91a by Jean Sibelius, and in the Dead March in Handel's Saul.
