"Tommy the Cat" is a song by the American funk metal band Primus, released on their second album, Sailing the Seas of Cheese.

In their live performances, Claypool does both parts himself; however, Tom Waits provided the voice of Tommy the Cat on the studio version from Sailing the Seas of Cheese.

A version called "Butters the Cat" was performed by Primus and Matt Stone at the South Park: 25th Anniversary Concert.

The animation featured a female cat strolling into an alley filled with numerous tomcats while the titular Tommy relays what happened.
