Fat Mike (real name Mike Burkett) is the vocalist and bass player of the popular punk rock band NOFX. Before starting NOFX in 1983 with Erick Sandin and Eric Melvin he used to play in False Alarm.

The name Fat Mike is a misnomer, as he isn't very obese. This confusion arose when the until-then quite thin Mike went away to college, and returned having gained a few pounds. The nickname stuck, even working its way into the name of his label, the cleverly named Fat Wreck Chords, one of the largest punk-affiliated record labels in the United States.
