Akseløya (English: Axel Island) is a long, narrow island (about 8.5 km long and 1 km wide) at the mouth of
Van Mijenfjorden, separating Van Mijenfjorden from
Bellsund. It is separated from the mainland by
Akselsundet to the north, and another narrow strait to the south. The islands are named after the schooner
Aksel Thordsen, which was chartered by
Adolf Erik Nordenskiöld for an expedition to
Svalbard in 1864.
