Hammerheart is the fifth studio album by Swedish extreme metal band Bathory.

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

AllMusic called the album an "unqualified triumph for the pioneering Swedish act.

"[2] Bathory Production HammerHeart Brewing Co. is a brewery located in Lino Lakes, Minnesota whose name and branding was influenced by the album.

According to co-founder Nathaniel Chapman, “All of our beer names are inspired by Norwegian lore and we want to keep that attitude.”[5] The themes of the brewery and its beer are focused on Norse and Celtic mythology, and heavy metal music.
