Minsener Oog, also Minser Oog or Minsener Oldeoog, is an uninhabited East Frisian island that belongs to the parish of Wangerooge in the north German district of Friesland in the state of Lower Saxony. It has been artificially enlarged through the construction of groynes.
The island is located just two kilometres southeast of the island of Wangerooge, from which it is separated by the creek of Blaue Balje, and four kilometres north of the mainland. The nearest towns on the mainland are Minsen and Schillig. The island's landowner is the Wilhelmshaven Water and Shipping Authority (Wasser- und Schifffahrtsamt Wilhelmshaven or WSA).
The name of the isle comes from the village of Minsen which lies opposite it on the mainland. There is a legend that Minsen was originally established on the island of Minsener Oog. The fishermen of the village caught a mermaid with the lower body of a fish, which then had the village drowned by a flood in revenge. Although this tradition is historically extremely doubtful, there is in Minsen a bronze sculpture of the Minsen Seewiefken, which is also the emblem on the coat of arms for the parish of Wangerland.
Oog is a town in the northern Sool region of Somalia. It is located between Burao and Las Anod.
