Hammerheart is the fifth studio album by Swedish extreme metal band Bathory. It continued the previous album Blood Fire Death's transition away from black metal to what became recognized as Viking metal, and is considered a cornerstone work of the genre. A music video was made for "One Rode to Asa Bay."

The song "Hammerheart" consists of the second theme in Gustav Holst's Jupiter, the Bringer of Jollity.

Quorthon dedicated the song "One Rode to Asa Bay", about the Christianization of Scandinavia, to C. Dean Andersson, who had earlier sent some of his books to Quorthon. The village's name in the song, Asa Bay, comes from the pseudonym Asa Drake which Andersson used in some of his books.
