Endelave is a Danish island in the Kattegat, north of Odense, off the coast of Funen, and west of Samsø.

Endelave and its surrounding seaside is important for many birds, both on domestic and international levels and it is therefore a Ramsar area.

[3] The reef 'Møllegrunden' Northwest of the island is an important resting and breeding site for many seals in the Kattegat sea.

The bay of Endelave is comprised by a large intertidal zone similar to the wadden sea area.

About ⅓ of the island itself is protected under the Natura 2000 plan, housing vulnerable and outstanding nature-types such as a heather moorland thicket, a beach-meadow and oak forests for example.
