The Geological Museum was a separate geology museum located at the northeast corner of the Copenhagen Botanical Garden, in Copenhagen, Denmark.

[1] In addition to housing exhibits, it also facilitates research and study as part of the University of Copenhagen, with some of the museum staff actively partaking in research worldwide.

[4] In 2004, it was merged with other natural history museums in Copenhagen and in 2020 the combined entity was officially renamed the Natural History Museum of Denmark.

The museum features changing exhibitions as well as permanent ones such as The Mineral Exhibition where the minerals are presented in a crystal chemical order starting with elements such as gold and silver and ending with silicates such as feldspar and zeolites.

Also on exhibit is a small rock from the Taurus-Littrow region of the Moon, brought back by the Apollo 17 astronauts in 1972.
