Heavy Rocks is the twenty-eighth studio album by Japanese experimental band Boris, released on 12 August 2022 by Relapse Records.

It is the third Boris album of this title, with the previous ones released in 2002 and 2011; all feature the band exploring hard rock and heavy metal sounds.

"[10] Metal Injection described the album, along with its predecessors of the same title, as an attempt by Boris "to go yard on arcane '70s rock and proto-metal screwballs with a pine tar-lined avant-garde/experimental clobbering apparatus.

"[9] Jon Hadusek of Consequence described the album as illustrating the band's love of "1970s hard rock and heavy psych" while retaining their well-known experimental impulses.

"[14] Thom Jurek of AllMusic concluded that "Boris continue to willfully and eagerly engage a tense musical restlessness that keeps them sounding unsettled, ambitious, often feral, and in a class of their own.
