Vigelsø is a small, uninhabited island in Odense Fjord, off the coast of Funen, Denmark.
With an area of 132 hectares (330 acres), it is the largest island in the fjord and an important breeding ground for waterfowl and rest stop for migratory birds.
Archeological findings have documented human activity on the island from the earliest times.
In 1990 the Danish Ministry for the Environment acquired the island to conduct ecological restoration and reforestation.
Vigelsø is a low-lying island with its highest point, Østerhoved, only reaching six metres above the sea.
