Copenhell is a heavy metal festival held annually at Refshaleøen in Copenhagen, Denmark, since 2010. It was one of the first open-air heavy metal festivals in Denmark.

Refshaleøen is a former industrial site in the harbor of Copenhagen, Denmark, originally on a separate island but now annexed to the larger island of Amager. For more than a hundred years, it was home to the shipyard Burmeister & Wain, which closed in 1996.
