艾草松鸡（学名：Centrocercus urophasianus）是北美洲最大的松鸡。它们生长在美国西部和加拿大的艾伯塔省和沙士吉万省南部长有三齿蒿的地方，种名也因此得来。甘尼森艾草松鸡最近被承认为一个独立品种，而在莫诺盆地的种群也可能是独立的品种。

成鸟有长而尖的尾部，和长至脚趾的羽毛。雄性成鸟在眼上方有黄色的斑点，背灰色，胸白色，喉部深棕色，腹黑色；颈上有两个黄色的囊，可以在求偶时充气以吸引异性。雌性成鸟背部和喉部为杂以白斑的棕灰色，腹部颜色较深。雏鸟背部颜色与雌性成鸟同，腹白色。

The greater sage-grouse (Centrocercus urophasianus) is the largest grouse in North America. Its range is sagebrush country in the western United States and southern Alberta and Saskatchewan, Canada. It was known as simply the sage grouse until the Gunnison sage-grouse was recognized as a separate species in 2000. The Mono Basin population of sage grouse may also be distinct.
