A dance organ is a mechanical organ built for indoor use in dance halls and ballrooms. It is quieter than a fairground organ and was popular mainly in mainland Europe, especially France, Belgium and the Netherlands.

In the early days before World War I, dance organs were used in France, Spain, Belgium and the Netherlands. After the war they remained common in Belgium and the Netherlands, where they stayed popular until World War II. The heyday of the dance organ came in the early 1900s with large instruments from Gavioli and Marenghi. In the 1910s Mortier expanded the sound with new pipes and percussion to suit modern popular music, and other makers like Hooghuys and Fasano followed. Many older sound schemes were updated by Mortier and others.

In Antwerp, Arthur Bursens built hundreds of small cafe organs that used rolls or book music. These were coin-operated via wall boxes and could play three or four tunes from a roll, rewinding after each tune. To meet demand, multi-tune rolls were often made. By the early 1920s, Mortier was the leading brand, followed by Gaudin of Paris (successors to Marenghi). The 1920s brought evolving sound schemes to match jazz-age dancing, and facade designs moved from Art Nouveau to Art Deco.

In the 1930s, instruments from the Decap firm in Antwerp rose in importance, and by the end of the decade Mortier and Decap had reached their peak in design and music. Dance organs came in many sizes; smaller ones were common in cafes and small venues and could be coin-operated remotely.

After World War II, Decap and others added new ideas and electronics, including Hammond-style tone generators, creating a partial replacement for traditional pipework. In the 21st century, a few manufacturers still build dance organs, often using modern tech. Some are wifi or MIDI operable, with electronic tones, dynamic percussion, karaoke options, and volume control.

Dance organs were designed to imitate the sounds of late 19th- and early 20th-century dance orchestras and bal-musette. Early music emphasized waltzes, two-steps and polkas, with softer solo playing as well as loud performances. As styles changed, organs added more chromatic notes, jazz percussion, and later Latin rhythms like mambo and cha-cha-cha. Visual effects were common, including lighting and display of mechanically operated accordions or a pretend saxophone. A famous example from the 1950s is the robot band by Decap Antwerp, with three robots playing percussion, sax, and a brass-like sound, often powered by a hidden Hammond organ.

Key makers in the dance organ story include Gavioli, Marenghi, Mortier, Hooghuys, Fasano, Decap and Bursens.
