Infectious Grooves (n., in-fek-shus groovz) are a funk metal band led by Suicidal Tendencies frontman Mike Muir. It also featured ex-Suicidal Tendencies, now Metallica, bassist Robert Trujillo, and ex-Jane's Addiction drummer Stephen Perkins.

Though Muir's sense of humor was often obvious with Suicidal Tendencies, Infectious Grooves often brought out a goofier type of humor: their albums contain comedy skits by a reptilian lover named Sarsippius.

The band can be seen (and heard) performing as the prom band in the 1992 Pauly Shore film Encino Man

In a recent interview, Muir reported that the Infectious Grooves are recording new material.
