The Ottó Herman Museum (Hungarian: Herman Ottó Múzeum) is the largest and most significant museum institution in Northern Hungary, located in the city of Miskolc. It is named in honor of Ottó Herman (1835–1914), a renowned Hungarian polymath whose work spanned zoology, ornithology, ethnography, archaeology, and politics, and who was closely associated with the region.
The museum's extensive collections cover a broad spectrum of disciplines, making it a prominent regional center for research and exhibition. Its primary areas of focus include natural history (with significant geological, mineralogical, paleontological, and zoological holdings), archaeology (particularly strong in prehistoric and ancient artifacts from the Bükk Mountains region), local history, ethnography, and fine arts. The natural history department is especially noted for its rich collections documenting the biodiversity and geological features of the Carpathian Basin.
Established in 1899 as the Museum of Borsod-Miskolc, it initially concentrated on local history and archaeological findings. Its scope and collections grew substantially over the subsequent decades. The institution was officially renamed the Ottó Herman Museum in 1953, reflecting its expanded mandate and paying tribute to the celebrated scientist. The museum operates multiple exhibition sites within Miskolc and across the Borsod-Abaúj-Zemplén county, hosting both permanent displays that explore the cultural and natural heritage of the area and a diverse program of temporary exhibitions.
