'''Mariaholmen''' is an islet in [Nathorst Land](/source/Nathorst_Land) at the mouth of [Van Mijenfjorden](/source/Van_Mijenfjorden) at [Spitsbergen](/source/Spitsbergen),  [Svalbard](/source/Svalbard). It is located south of [Akseløya](/source/Aksel%C3%B8ya), between Akseløya and [Måseneset](/source/M%C3%A5seneset).
