Helictotrichon, or alpine oatgrass,[2] is a genus of perennial flowering plants in the grass family.[3][4][5][6] The genus name comes from the Greek heliktos meaning twisted, and trichos meaning hair, referring to the shape of the awn.[7]

Most of the species are native to Africa and Eurasia with a few species in North America. Helictotrichon sempervirens is widely cultivated as an ornamental.[8][9][10]
