Grankullaviken (or Grankullavik) is a shallow[1] bay at the northern tip of Öland, Sweden, located in Böda socken, Borgholm Municipality. The bay is almost completely enclosed by two headlands and a few small shoal islands (Stora grundet, Borren, and Lilla grundet). Grankullavik is also the name of a village on the bay. The lighthouse Långe Erik on the Stora grundet island is officially named Ölands norra udde (Öland's northernmost point), even though the western headland extends a bit further north than the island upon which it stands. The eastern headland is the site of the windswept forest and nature reserve Trollskogen.
