Garry Denis Peterson (born May 26, 1945) is a Canadian-American drummer. Peterson was originally a "child prodigy" drummer, backing many popular acts in the 1950s, but is best remembered as an original member of The Guess Who. He served as the band's drummer from 1962 to 1975.

He later joined Bachman–Turner Overdrive until he was fired a few years later. He joined an unauthorized Guess Who band put together by original bassist Jim Kale. Peterson and Kale toured under the Guess Who name for over 40 years, until stopped in 2004 by lawsuits from Burton Cummings and Randy Bachman.
