Graellsia is a genus of small perennial sub-caespitose herbs in the family Brassicaceae.[1] Most of the species are found in Iran and Afghanistan, with one occurring in Turkey, and one in the High Atlas of Morocco.[1] They are typically found in shady crevices of calcareous rocks at altitudes of 1,000–3,600 metres (3,300–11,800 ft).[1]

The genus was erected in 1842 by Pierre Edmond Boissier, commemorating the Spanish zoologist Mariano de la Paz Graëlls y de la Aguera.[1] It initially contained only , which had previously been placed in Cochlearia. New species were gradually added, and was moved to Graellsia, having previously been the only species in Draba sect. Helicodraba.[1] 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.[2]

It contains the following species:[3]
