''Graellsia'' is a genus of small perennial sub-caespitose herbs in the family Brassicaceae / Cruciferae. Most of the species are found in Iran and Afghanistan, with one occurring in Turkey, and one in the High Atlas of Morocco.〔 They are typically found in shady crevices of calcareous rocks at altitudes of .〔 The genus was erected in 1842 by Pierre Edmond Boissier, commemorating the Spanish zoologist Mariano de la Paz Graëlls y de la Aguera.〔 It initially contained only ''Graellsia saxifragifolia'', which had previously been placed in ''Cochlearia''. New species were gradually added, and ''G. hederifolia'' was moved to ''Graellsia'', having previously been the only species in ''Draba'' sect. ''Helicodraba''.〔 Subsequent investigations using molecular phylogenetics have questioned the grouping of ''G. hederifolia'' and ''G. saxifraga'', and ''G. hederifolia'' may need to be restored to the genus ''Draba''.
