Carillons, musical instruments of bells in the percussion family, are found throughout Belgium. Several institutions maintain registries on the location and statistics of carillons. Some registries specialize in counting specific types of carillons. For example, the War Memorial and Peace Carillons registry counts instruments which serve as war memorials or were built in the name of promoting world peace (and tracks five in Belgium); the counts carillons throughout the country, along with the rest of the world.
Two Belgian carillon associationsthe Flemish Carillon Association and the Walloon Carillon Associationcount carillons in their respective regions. According to their registries, there are 94 carillons in Belgium: 70 in the Flemish Region, 22 in the Walloon Region, and 2 in the Brussels Capital Region. They are distributed across 77 different cities; several are located within the same city, and two are even within the same buildingat St. Rumbold's Cathedral in Mechelen. The population has a wide range in total weights, with bourdons spanning between . They also span a wide range of notes, from 21 (which the Flemish association considers a carillon despite failing its definition that requires at least 23) up to 64. Many carillons were constructed over several centuries by several bellfounders; a minority are constructed entirely by a single bellfounder. The majority of carillons are transposing instruments, and often transpose such that the lowest note on the keyboard is B or C.

The smaller is located at the Palace of the Nation, Belgium's federal parliament building. Constructed in the 20th century, these carillons are much newer relative to others in the country. Brussels once had nine carillons in 1541; none survived past 1914.
