Agrostis vinealis (Chinese: 芒剪股颖; pinyin: mang jian gu ying) is a species of grass known by the common names brown bentgrass and brown bent, which can be found from Russia to Mongolia, into China and even Pakistan, and India. It was introduced to Greenland and Alaska.

Brown bent is one of the Perennial grasses, loosely to densely tufted, growing up to 70 cm tall; all parts hairless, dark to bluish-green. A. capillaris has rhizomes and occasionally stolons; A. vinealis lacks stolons. Ligule: short, membranous and translucent. A.capillaris ligule < 3 mm long; A.vinealis ligule ≥ 3 mm long. Leaf blade flat, short and narrow, 100-150 x 1-5 mm, ribs regular, margins slightly rough; emerging leaf rolled. Flowers: panicle 8-18 cm long, usually open in arrangement; spikelets 1.8-2.7 mm long, 1-flowered; glumes subequal or unequal; awn very variable; lemma 1.4-2.2 mm long; in A.vinealis the palea is under half the length of the lemma; in A.capillaris the palea is greater than half the length of the lemma. Fruits: dispersed by wind and by livestock; viability in soil may be 5 years or more. Typically found in areas with low soil fertility.
