Orgelmakerij Reil is a Dutch organ-building company based in Heerde. The family business was founded in 1934 and has been led by Hans Reil, the third generation, since 2001. Since 1985, more than 60 organs have been built or restored. Reil is considered one of the leading Dutch organ-building companies for the restoration of historical organs. Numerous instruments have been exported to countries including Austria, Norway, and Japan.

Johann Reil (born April 6, 1907; died May 5, 1960) was born in Munich. He learned organ building starting in 1922 under Albert Moser and Leopold Nenninger in his birthplace. From 1928 to 1929, he deepened his skills and knowledge in Augsburg and with the organ-building company Zimmermann & Schäfer in Basel. In 1929, he moved to the Netherlands to build a cinema organ for the Tuschinski Theater in Amsterdam on behalf of Zimmermann & Schäfer. From 1929 to 1934, he worked for Valckx & Van Kouteren, Flentrop Orgelbouw, and J. de Koff & Zoon in Utrecht. In 1934, he started his own workshop in Rotterdam, known as Eerste Nederlandsche Orgelonderdeelen Fabriek, supplying organ parts to other companies. In 1937, he moved to Heerde, where he had met his future wife in 1932. He married Dien de Brake (1913–2008) in 1938, and they later had three children. Reil became a Dutch citizen and completed his first new organ for the Hervormde Kerk in IJmuiden-Oost in 1938. Starting in 1948, he built organs with mechanical action, such as the one for the Gereformeerde Kerk in Arnemuiden.

After Johann Reil's death, his workshop was continued by his sons Han (1939–2024) and Albert (1942–2001), both of whom had learned organ building in their father's workshop. Han Reil specialized in voicing with Orgelbau Kuhn, while Albert Reil focused on pipe making with Busch in Herten. Influenced by their contacts with Klaas Bolt and the Schnitger Conference in Groningen in 1969, the brothers decided to pursue historically oriented organ building in the tradition of the 16th to 18th centuries. This approach led to the creation of organs in the Ontmoetingskerk in Dieren (1970) and replicas of the Schnitger organ of the Jacobikerk in Uithuizen (1701) for Scheveningen (1973), the Bielfeldt organ in Scharmbeck for the Tokyo College of Music (1979), and the Steevens-Hinsz organ in Tzum (1765) for the Immanuel-Kerk in Ermelo (1981). These replicas received both great admiration for their quality and significant criticism.

Between 1983 and 2008, the company built nine new organs in Austria and restored the famous Andreas Putz organ (1634) in the Schlägl Monastery in 1989/1990. Since 1979, 14 new organs were delivered to Japan and 13 to Norway. In addition to church organs, the company built more than 40 house organs with eight to twelve registers by 2014. The firm, which expanded under the name Gebroeders Reil, acquired the business of Ernst Leeflang (Apeldoorn) in 1994. A year later, the company moved to a new workshop in Heerde.

When Albert Reil fell ill and passed away in 2001, Johann Reil's grandson Hans Reil (born 1968), son of Han Reil, took over the company. Hans had graduated as a diploma engineer from the Technical University of Enschede in 1992, joined the family business in 1993, and specialized in voicing.
