Smegma is an American experimental noise group formed in Pasadena, California in 1973 and currently based in Portland, Oregon. Originally part of the Los Angeles Free Music Society (LAFMS) movement of the 1970s, Smegma is one of the few music collectives of that era still active today. Author Richard Meltzer became their vocalist in the late 1990s. The group was included in the Nurse with Wound list and more recently was featured on the cover of the August 2006 edition of The Wire.
