Hermann Raphaëlis (ca. 1515–1583) was a Dutch-born organ builder who made significant contributions to the field of organ construction in Denmark during the 16th century. He was likely born around 1510-20, the son of organ builder Gabriel Raphael Rottensteen. Around 1550, Raphaëlis was summoned to Denmark to construct the organ in Roskilde Cathedral, a prominent project that established his reputation in the region. He also built a two-manual organ for the chapel of Copenhagen Castle and at least one positive organ, showcasing his craftsmanship and expertise in organ building.

Later, Raphaëlis moved to Saxony, where he continued his work and built chapel organs for Elector Augustus of Saxony, who was the son-in-law of the Danish-Norwegian Queen Dorothea. It is believed that the organ in Queen Dorothea's chapel at Sønderborg Castle might be one of Raphaëlis' works. His contributions to organ building in both Denmark and Saxony highlight his significant impact on the development of organ music and construction during the Renaissance period.
