HRD is a musical group from Portland, Oregon, featuring members Keegan Quinn, Big Nutz, and Raw Dillz. Since their 2011 debut, they serve up tracks thick with heavy, textured beats and dense webs of rhyme.

Prior to the release of the second album, the group was also known by the longer version of the name, Hundred Round Drum. Keegan and Big Nutz were also previously involved with Portland gangsta rap group 5 Oh Trees.
