Upland game bird is an American term which refers to non-waterfowl game birds in groundcover-rich terrestrial ecosystems above wetlands and riparian zones, which are commonly hunted with gun dogs.

Gun dogs or bird dogs are types of hunting dogs developed to assist hunters in finding and retrieving game, typically various fowls that are shot down on the flight. The term hunting dog is broad and includes all breeds and skills of hunting canines, but "gun dogs" refers to canines that are trained to work alongside a loud firearm while hunting or retrieving game. Gun dogs are divided into three main categories: pointers and retrievers, setters and spaniels, and water dogs.
