Dimorphotheca is a genus of plants in the family Asteraceae, native to southern Africa. ^[3] is one of eight genera of the Calenduleae, with a centre of diversity in Southern Africa. Species are native to Botswana, Eswatini, Lesotho, Namibia, South Africa, and Zimbabwe. ^[1] Some species can hybridize with Osteospermum , and crosses are sold as cultivated ornamentals.

The name Dimorphotheca is derived from the Greek: di (two) morph (shape) theka (receptacle), referring to the dimorphic cypselae, a trait inherent to members of the Calenduleae. ^[4] Plants of this genus usually have bisexual flowers.
