Gerrardanthus is a genus of flowering plants native to tropical Africa and South Africa, first described by William Henry Harvey (1811–1866), and named in honor of William Tyrer Gerrard (died 1866 in Mahavelona, Madagascar), botanical collector in Natal and Madagascar in the 1860s.

Gerrardanthus is a perennial climber, with height up to 5 m, rising from a swollen, tuberous base with a thickness of up to 1.5 m. Stems are herbaceous but becoming woody and grey-barked as they age.
