Gymnocalycium, commonly called chin cactus, is a genus of about 70 South American species of cacti. The genus name Gymnocalycium (from Greek, "naked calyx") refers to the flower buds bearing no hair or spines.

Their main area of distribution is Argentina, part of Uruguay, Paraguay, southern Bolivia and part of Brazil. Most species are rather small varying from 4 to 15 centimetres in size. They are popular for their easy flowering habits, and the flowers are generally brightly coloured.

The Ruby Ball or Moon Cactus, Gymnocalycium mihanovichii 'Hibotan', is a mutant that lacks chlorophyll
