Firebird (Russian: жар-птица, zhar-ptitsa) is a magical glowing bird from a faraway land, which is both a blessing and a bringer of doom to its captor.

The Firebird is described as a large bird with majestic plumage that glows brightly emitting red, orange, and yellow light, like a bonfire that is just past the turbulent flame. The feathers do not cease glowing if removed, and one feather can light a large room if not concealed. In later iconography, the form of the Firebird is usually that of a smallish fire-colored peacock, complete with a crest on its head and tail feathers with glowing “eyes”.

A typical role of the Firebird in fairy tales is as an object of a difficult quest. The quest is usually initiated by finding a lost tail feather, at which point the hero sets out to find and capture the live bird, sometimes of his own accord, but usually on the bidding of a father or king. The Firebird is a marvel, highly coveted, but the hero, initially charmed by the wonder of the feather, eventually blames it for his troubles.
