A bird hide (or hide, also known as a blind or bird blind in North America) is a shelter, often camouflaged, that is used to observe wildlife, especially birds, at close quarters. Although hides were once built chiefly as hunting aids, they are now commonly found in parks and wetlands for the use of bird watchers, ornithologists and other observers who do not want to disturb wildlife as it is being observed.

A typical bird hide resembles a garden shed, with small openings, shutters, or windows built into at least one side to enable observation.
