Downset. (originally called Social Justice) is an American rap metal band from Los Angeles, California. The band's music blends hip hop, funk, hardcore punk, and heavy metal with 'socially aware lyrics'.

In 1994 Downset. began gaining popularity in Europe after touring there with Biohazard and Dog Eat Dog, followed by a tour with Pantera and The Almighty later that year. They released their self-titled effort in the same year. A year later, Downset. returned to Europe with Sullen for a massive headlining tour. In 1995 they also appeared at some major rock festivals throughout the continent including Roskilde and Dynamo.

The band is still regarded as a noteworthy influence on the then-nascent nu metal and rap metal subgenres. In addition to headlining the second stage at Ozzfest in 1997, Downset. toured with prominent bands such as Linkin Park, Pantera, Slayer, Metallica, Red Hot Chili Peppers, Korn, Snoop Dogg, Testament and Anthrax.
