Stapelia gigantea is a species of flowering plant in the genus Stapelia of the family Apocynaceae. Common names include Zulu giant, carrion plant and toad plant. The plant is native to the desert regions of South Africa to Tanzania.

Stapelia is a genus of low-growing, spineless, stem succulent plants, predominantly from South Africa with a few from other parts of Africa. Several Asian and Latin American species were formerly included but they have all now been transferred to other genera. The flowers of certain species, most notably Stapelia gigantea, can reach 41 cm (16 inches) in diameter when fully open. Most Stapelia flowers are visibly hairy and generate the odor of rotten flesh when they bloom.
