The Naturmuseum Dortmund is a Dortmund museum dedicated to natural history and science. The museum's collection originates from the teacher Edgar Weinert, who began to bring it together in the early 1900s. In 1912 he made it accessible to the public, becoming the first director of the new museum. The museum was badly hit with the Second World War: with the bombing of the city, almost 90% of the finds were destroyed.

The museum collection contains exhibits relating to the fields of biology, geology and paleontology. The zoological exhibition offers an overview of the biological system with a special focus on local fauna and flora. An entire section of the museum is also dedicated to mushrooms. Then there is the aquarium, where the different species of fish that live in the Möhnesee river are shown. The geoscientific collection provides an overview of minerals and sedimentary rocks. The museum's mineral collection displays minerals from North Rhine-Westphalia on the one hand and finds from Tsumeb in Namibia on the other. The paleontological department is home to a wide variety of fossils. The reconstruction of a mine in the museum cellar sheds light on the world of miners and their work.
