Bob Roll is an American former professional cyclist, author, and television sports commentator. He was a member of the 7-Eleven Cycling Team until 1990 and competed for the Motorola Cycling Team in 1991. In 1992 Roll moved to Greg LeMond's Z team and added mountain biking to his racing accomplishments. Roll continued racing mountain bikes professionally through 1998. Roll is known in the cycling world, and to his global cable television fans, fondly, as "Bobke".

He has written Bobke: A Ride on the Wild Side of Cycling, Bobke II, and two Tour de France Companion volumes. He has also had many columns published in VeloNews.

Roll continues to enjoy riding road and mountain bicycles for recreation, and is a member of the veteran cable television broadcasting team (along with Phil Liggett, MBE and Paul Sherwen) who serve as road cycling expert-commentators for the NBC Sports Network cable network's coverage of the Tour de France, Giro d'Italia, Paris–Roubaix, Tour of California, and other international cycling road races.

Roll has appeared in a series of Road ID Tour de France television commercials as himself, riding a bus along with "Tour Mania" (a costumed-disguised rowdy faux rock group played by well-known professional cyclists).
