Hammerfest is a music festival held annually at Pontin's Holiday Village, Prestatyn, Wales; it is not related to a music festival of the same name hosted by white supremacist groups. The festival is owned by emc3i Ltd, sponsored by their music magazine Metal Hammer and run by the organizers of the Hard Rock Hell festival. Because the festival is held at a holiday camp, the organizers can make use of pre-built venues and stages, and attendees can stay in the on-site accommodation. This enables the festival to be held during the winter/spring months when outdoor camping is not desirable. Each edition of the festival so far has sold out the holiday camp, which has a capacity of 4,000. From 2013, Hammerfest will be moving to the Haven site in Pwllheli, Hafan y Môr Holiday Park as the festival has outgrown the site at Prestatyn.

The festival takes place in March 2016 and is set to showcase bands such as Exodus, Turisas, Evile and more bands.
