Duvalia is a plant genus in the tribe Stapeliae, milkweed subfamily Asclepiadoideae, in the family Apocynaceae (dogbane). The genus was first described in 1812, named after the French physician and botanist Henri-Auguste Duval (1777-1814). It can be found on the Arabian peninsula, in tropical Africa and South Africa.

The Duvalia species are succulent, perennial plants with low, planar growth. The shoots are clavate, cylindrical to spherical, in cross-section four-, five-or six-edged, and to about 10 inches long. They can range from green, gray to mottled reddish in color. The flower stems are long and bare. The hermaphroditic flowers measure 1-5 cm in diameter, and have five parts. The crown is yellow ocher, brown, red to dark purple. The five corolla lobes are flat or folded along the middle nerve.
