De Zegge is one of two artificial islands located in the Wolderwijd, a shallow bordering lake situated between the provinces of Flevoland and Gelderland in the Netherlands. The island lies in the southern part of the lake, near Zeewolde's marina.

Together with De Biezen to the north, De Zegge was designed to support biodiversity and help mitigate erosion within the lake.

The Wolderwijd, along with the adjacent Nuldernauw, has been designated a Ramsar wetland of international importance since 2000, recognized in part for its significance to species such as the whooper swan and common pochard.

De Zegge's position in this protected ecosystem makes it a point of interest for those exploring the lake by water or along its shores.
