Spiekeroog is one of the East Frisian Islands, off the North Sea coast of Germany. The only village on the island is also called Spiekeroog. The island is part of the Wadden Sea World Heritage Site by the UNESCO and the Wittbülten National Park.
The island covers an area of 18.25 km2, the shortest distance to the mainland is 5.7 km. The island is, with the exception of fire and rescue vehicles, free of cars. A daily ferry service from the harbour of Neuharlingersiel connects the island with the German mainland. The island is separated from neighbouring Wangerooge by a gat known as the Harle.
The origin of the name "Spiekeroog" is disputed. Today, most of its people tend to believe that it is a translation of "storage island".
