The Schuelke Organ Company was a Milwaukee, Wisconsin-based pipe organ builder. Schuelke Organs operated in the later 19th and early 20th centuries.

William Schuelke was a Prussian immigrant who came to the United States in 1874. Schuelke's contributions to organ building included inventing the electric motor powered bellows crank, for which he received a patent. This was a major improvement over existing hand-cranked bellows.

The Schuelke Organ Company ceased operations in the early 20th century. Today, few of the organs his company produced exist intact.

A yearly free organ recital is held at Saint Francis of Assisi Catholic Church, Milwaukee on the first Sunday of November to showcase its 1885 Schuelke pipe organ.
