A tiny island in the Oslo fjord, Norway. It is located just outside Sandvika in Bærum and visible from E-18 when driving eastwards through Sandvika. Its name is probably a nickname that stuck, because older maps does not show this island to have any name at all. When you stand ashore looking towards Danmark, you can make out the contours of Skagerrak on a very small scale. This is likely the reason for the island's name.

The size of Danmark is just over 400m2 and has two boat sheds. There are no inhabitants on the island.

June 10, 2004, Major Update: The boat sheds have been demolished!
