A mounted band is a military or civilian musical ensemble composed of musician playing their instruments while being mounted on an animal. The instrumentation of these bands are limited, with the musician having to play their instrument, as well as steer the animal to the designated location. Most mounted bands, therefore, use instruments that can easily be held, such as bugles, horns, and Fanfare trumpets. Timpani and glockenspiels are also a common feature, usually located at the head of a band. Although a band that is mounted on any member of the families Equidae and Camelidae are considered to be a mounted band, horses are most commonly used, mostly being employed in military bands in Europe, North and South America, and some parts of Asia.

Mounted bands in most cases are variants of military bands and are meant for the cavalry, and only several are in service today in various parts of the world. The main current functions have been providing musical support for ceremonial events, for civic events, and perform at military and police observances such as funerals and military and police academy graduations. Similarly to military and police, and Pipe bands, the musical repertoire is primarily based on ceremonial compositions and marches, with a high percentage also including honors music such as fanfares. A Cavalry march is used as military marching music in the movement of mounted troops. The marches of mounted bands are written in ⁶
₈ time, rather than the ²
₄ or ⁴
₄ time of the infantry.

Mounted bands were originally established at sometime around the 12th century, during the crusades, with these newly established bands being incorporated into infantry bands. The idea then caught on in Central Europe before being used by the Ottoman Empire, who also created the first military band in the world. The use of timpani, trumpets, and bugles in these bands played an important role in the middle of the 15th century, when they were deployed to the front lines to motivate the mounted cavalry in battle and in parade.

The seniormost band of the armed forces, the Alto Peru Fanfare Brass Band of the Regiment of Mounted Grenadiers, is the official mounted brass band in service to the President of Argentina in his/her capacity as Commander in Chief of the Armed Forces of the Republic. The brass band was founded in 1929. Despite it being a mounted band, it can also perform with the regiment while dismounted.

Another notable mounted band in the Argentine Army is the Mounted Band of the 4th Armoured Cavalry Regiment "General Lavalle's Cuirassiers", which wears uniforms similar to those of the French Republican Guard. Similar to the Alto Peru Band, despite it being a mounted band, it can also perform with the regiment while dismounted.

A new mounted band was raised in 2018 to serve as the ceremonial musical unit of the Mounted Operations Group of the 1st National Gendarmerie Region, Argentine National Gendarmerie.

The group is directed by its founder Leonardo Fuks, an oboist, multi-instrumentalist and professor of music acoustics at Rio de Janeiro Federal University.
