Nidingen is a Swedish Kattegat sea area skerry with a lighthouse station.

The Danes had lit primitive navigation fires on the island before, and also built a "vippefyr", but now it became one of Sweden's earliest light stations.

In 1973, an automatic rotation of the lens was installed around the clock while the lighting of the lamps was controlled by photocells.

It was reported several times in the 2000s that the lighthouse could be deactivated when it was no longer considered necessary for shipping,[4] but it remained in use.

In 2019 it was reported that the Swedish Maritime Administration, Sjöfartsverket, plans to convert it to be powered by solar cells.
