Gunniopsis is a genus of flowering plants in the iceplant family, Aizoaceae. These plants are found in areas of inland Australia. Gunniopis comprises 14 species that were once members of the genera Aizoon, Gunnia and Neogunnia. The name of the genus honours the botanist and politician Ronald Campbell Gunn. The genus was first formally described by the botanist Ferdinand Pax in 1889 in Engler and Prantl's work Die Naturlichen Pflanzenfamilien. The name is derived from the Greek word opsis meaning resembling which alludes to the resemblance of the genus to the genus Gunnia.
