Mardalsfossen is a waterfall in Molde Municipality in Møre og Romsdal county, Norway. It is sometimes referred to as one of the tallest waterfalls in Europe. The falls are on the Mardøla river which flows out of a hanging valley into the lake Eikesdalsvatnet, about 2 kilometres (1.2 mi) northwest of the village of Eikesdalen. The waterfall was depicted in the coat of arms of the old Nesset Municipality.
