American march music is march music written and/or performed in the United States.

The true "march music era" existed from 1850 to 1940s as it slowly became shadowed by the coming of jazz. Earlier marches, such as the ones from George Frideric Handel, Wolfgang Mozart, and Ludwig van Beethoven tended to be part of a symphony or a movement in a suite. Despite the age of these marches, the history it holds and its performance in the United States, they are generally not thought of as "typical American march music".

The origins of European and American march music can be traced to the military music of the Ottoman Empire. The martial purpose of the music was to regulate the functioning of armies in the field by communicating orders, and keeping time during marching and maneuvers. The extensive use of percussion, such as cymbals, was also used for psychological effect as their use, especially in Western Europe, was unknown and had the capacity to frighten opponents. Indeed, the subsequent use of cymbals and other such percussive instruments in European 'classical' music was a direct importation from the Ottomans. In the early 18th century, Europeans were first exposed to this type of music and interest would continue to build into the early 19th century when a vogue for Turkish marching bands swept through Europe. Pieces displaying this Turkish influence can be found in the works of Mozart, Haydn, and Beethoven with a notable example being "Turkish March" by Beethoven (part of Op. 113): Overture and incidental music for Die Ruinen von Athen.

The origins of march music began before the Gunpowder Age during which armies would maintain their troops' morale by marching with music playing, whether that be from the beat of a drum or fife. American march music showed during the American Revolutionary and earlier wartime conflicts, in which a fife and snare drum would play while the troops marched to battle. This is why it can be said that march music is a military's music.
