Sekken is an island in Molde Municipality, Møre og Romsdal county, Norway. The island is located in Romsdal Fjord, at the mouth of the Langfjorden. The island lies about 4 kilometres (2.5 mi) south of the island of Bolsøya and about 1 kilometre (0.62 mi) west of the historic island of Veøya. There are no road connections to the 18.7-square-kilometre (7.2 sq mi) island except for a ferry connection between the town of Molde and Seterneset on the island. The proposed Langfjord Tunnel includes a possible branch off the main tunnel under the Langfjorden that would connect Sekken to the mainland by subsea road tunnel.
