Fur is a small Danish island in the Limfjord at the northern tip of the Salling peninsula. Fur has under 900 inhabitants. The island covers an area of 22 km². It is located at 56°49′N 09°01′E.
The island is linked to the mainland through a 24 hour ferry, the Sleipner-Fur ferry, sailing from Branden. The crossing of the Fursund takes 3–4 minutes.
The island is renowned for its deposits of diatomite, known in Danish as moler which is used for cat litter. Fossil hunting is a popular activity on the island, and the fossils one can find in the moler can be more than 55 million years old. A museum on the island features exhibits relating to the island, particularly fossils.
In 2010, readers of the Danish newspaper Kristeligt Dagblad voted for "Denmark's most wonderful island" and chose Fur ahead of Læsø and Ærø.
The Island hosts Innovation Fur, an ambitious development project running from 2011 to 2015. The overall vision is to demonstrate how modern technology, digitalisation, and energy saving solutions may contribute to the development of the sustainable welfare society of the future. Innovation Fur will play an important role in the demonstration of technology developed by the Greencom Project.
