Biology Museum, Biology museum in Mergangsan, Yogyakarta, Indonesia

The Biology Museum at Gadjah Mada University is a natural history museum in Yogyakarta, Indonesia, displaying thousands of preserved specimens from the animal and plant kingdoms. The collection covers zoological and botanical materials prepared through wet preservation, taxidermy, and skeletal arrangements, organized for systematic viewing.

The museum grew from two separate collections: the Museum Zoologicum, started in 1964 in a room at the UGM Sekip campus under Prof. drg. R. G. Indrojono, and the Herbarium, led by Prof. Ir. Moeso Suryowinoto at Jl. Sultan Agung 22. Both were managed by the Faculty of Biology, then based at Ndalem Mangkubumen, Ngasem. On 20 September 1969, during the faculty's anniversary, Rector Prof. Dr. Soeroso H. Prawirohardjo inaugurated the combined Museum Biologi, which opened to the public on 1 January 1970.

The museum's name comes from its parent faculty, and its collection grew from two separate university cabinets: the Museum Zoologicum and the Herbarium. Visitors can see dried and wet plant preparations, which make up about 70% of the roughly 3,700 specimens, alongside animal specimens. The museum is run by the Faculty of Biology at Gadjah Mada University.

The museum sits on Sultan Agung Road in Yogyakarta and is open on several weekdays, with closing times that vary depending on the day. Checking the current schedule before visiting is a good idea, as it gives you enough time to walk through the full collection without rushing.

Among the museum's featured specimens is a mounted Javan rhinoceros (Rhinoceros sondaicus), a species with fewer than fifty individuals left in Ujung Kulon National Park. The collection also holds a preserved golden cat (Catopuma temminckii) and a mimi-mintuna, an arthropod of mangrove and swamp waters.
