Downpour is the name used by several different acts in hardcore and related underground styles, including a Connecticut hardcore band formed in 2009, a fast hardcore band from Central Queensland in Australia, a band from Tampa, Florida that later relocates back to the WV/KY/OH area, and a powerviolence band from Dallas, Texas. One listing also identifies Downpour as an experimental drum and bass project by Hood frontman Chris Adams.

The name appears across a range of scenes and locations, with releases and web presences associated with Myspace and Bandcamp. The Connecticut group describes itself as a five-piece hardcore band, while the Australian act is identified specifically as a fast hardcore band. Another Downpour is linked to the hardcore and metalcore/powerviolence world through its Dallas identification, and the Tampa version is tied to the US Midwest/Appalachian region through its WV/KY/OH origins and relocation.

The reference to Chris Adams connects Downpour to Hood, and places it within a separate experimental drum and bass context rather than the hardcore bands of the same name.
