Joseph Silberbauer (died 1805 in Znojmo) was a South Moravian organ builder who worked in northern Lower Austria and southern Moravia during the last third of the 18th century. His successors were Ignaz Reinold and Benedikt Latzl, who each continued the business in Znojmo.

Little is known about his biography. It is presumed that Silberbauer was a student of Ignaz Florian Casparides in Znojmo and took over his workshop. He took the citizen's oath there on January 8, 1768. He is described as an organ builder from Znojmo, although this has not been documented. Ignaz Reinold (1777–1848) learned organ building from Silberbauer and took over his workshop when his master went blind and died in 1805.

Around 55 of Silberbauer's works are documented. He primarily built two-manual organs with Rückpositiv and some gallery organs. His organs are crafted with the highest level of craftsmanship and artistic skill and are thoughtfully designed. His best-preserved instruments are in Dürnholz, Grusbach, and Dyje. In some of his works, Silberbauer used the broken octave with F-sharp and G-sharp in the bass octave.
