Hellnar (Icelandic pronunciation: [ˈhɛtlnar̥]) is an ancient fishing village, a cluster of old houses and buildings situated close to Arnarstapi on the westernmost part of the Snæfellsnes peninsula, Iceland.

Although Hellnar village used to be a major port of call for fishing vessels and the largest and busiest centre of fishing and fishing vessels in Snæfellsnes, there were also a few farms in and around Hellnar village along with quite a few semi-permanent and short-stay living quarters for seamen and the migrating workforce.

Hellnar village can in all probability trace its function as a major port of call back to the Middle Ages, and the oldest written source of it being describes as a fishing port dates back to 1560.

This same year the buildings and farms of Hellnar are listed as numbering 38 altogether, of which 7 farms are listed as agricultural farms, 11 as having fisheries and fisheries-related functions, and 20 as listed as being semi-permanent or short-stay lodgings for the migrating work force and displaced persons.

On the beach some spectacular rock formations are to be seen, one of which is a protruding cliff called Valasnös, which reaches across the ocean front and into the sea.
