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

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.

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.
