Bonus Fat is a compilation album by the American punk rock band the Descendents, released in 1985 through New Alliance Records. It combines the band's 1979 debut single "Ride the Wild" / "It's a Hectic World" with their 1981 Fat EP and the track "Global Probing" from the 1981 New Alliance compilation Chunks. The compilation's cover combines guitarist Frank Navetta's illustration for the Fat EP with a caricature of singer Milo Aukerman drawn by Jeff "Rat" Atkins.
