草原鸡是指草原松鸡属下的两个物种，即大草原榛鸡及小草原松鸡。

草原鸡主要分布在北美洲，大草原榛鸡喜欢生活在高草草原，而小草原松鸡则生活在沙丘及草原中。草原鸡并非候鸟，都是区域性的鸟类，会保卫自己的领土。大草原榛鸡约长36厘米，比小草原松鸡稍大，色泽亦较为深色。

草原鸡现时的保育状况被分类为易危，而部份地区的草原鸡，包括新英格兰草原松鸡或奥氏角雉，都已经灭绝或处于濒危状况。

Tympanuchus is a small genus of birds in the grouse family. They are commonly referred to as prairie chickens. The genus contains three species:

All three are among the smaller grouse, from 40 to 43 cm (16 to 17 in) in length. They are found in North America in different types of prairies. In courtship display on leks, males make hooting sounds and dance with the head extended straight forward, the tail up, and colorful neck sacks inflated (shown in the photograph at upper right). Tympanuchus comes from Ancient Greek roots and means "holding a drum"; it refers to the membranous neck sacks and the drum-like call of the greater prairie-chicken.
