The ruffed grouse (Bonasa umbellus) is a medium-sized grouse occurring in forests from the Appalachian Mountains across Canada to Alaska. It is the most widely distributed game bird in North America.^[2] It is non-migratory. It is the only species in the genus Bonasa.

The ruffed grouse is sometimes incorrectly referred to as a "partridge", an unrelated phasianid, and occasionally confused with the grey partridge, a bird of open areas rather than woodlands.^[3]

The ruffed grouse is the state game bird of Pennsylvania, United States.^[4]
