Galloping Goose Motorcycle Club (GGMC) is a one-percenter motorcycle club that began around a motorcycle racing team and friends based out of Los Angeles, California in the United States in 1942. The group was informal and not chartered until 1946. Soon after, the organization spread out from southern California, establishing chapters in Illinois, Missouri, Montana, Indiana, Wyoming, Kansas, Mississippi, Louisiana and Florida. The club has a close relationship with El Forastero Motorcycle Club.
