Michael Burkett, more commonly known as Fat Mike, is the lead singer and bassist of the California punk band NOFX, as well as bass player for Me First and the Gimme Gimmes. As Misfit Mike, he played in a band called False Alarm before founding NOFX in 1983 with Erik Sandin and Eric Melvin. He's also the owner of Motor Studios in San Francisco, California. Mike lives in San Francisco with his wife for 14 years, Erin, and their young daughter, Darla.

The nickname "Fat Mike" originated as a misnomer - when the somewhat thin Mike went away to San Francisco State University he returned having gained a few pounds. He was slightly heavier than the broomstick-thin punk rock crowd, and the nickname stuck. Today Mike regards himself as "Not that fat."
