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 spine, 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]

Many species once considered part of Helictotrichon are now regarded as better suited to other genera. A large number are now in Helictochloa with smaller numbers of species in Amphibromus Arrhenatherum Avenula Danthoniastrum Duthiea Tricholemma and Trisetum.
