Richard Ramirez is an American noise music artist from Houston, Texas, recording and performing both as a solo artist and as part of several groups and Houston Noise Bands, including Black Leather Jesus, Priest in Shit, An Innocent Young Throat-Cutter, Oasis of Fear, Last Rape and the "static noise" solo project Werewolf Jerusalem. He is notable for being one of the earliest American harsh noise artists.

Ramirez, though extremely prolific, draws a distinction between his relatively few professionally printed CDs and LPs and the many CD-Rs and tapes he produces for smaller record labels. He has done collaborations and split releases with many figures in the noise field, including Merzbow, Emil Beaulieau, Skin Crime, and MSBR.
