Didierea is a genus of succulent flowering plants in the family Didiereaceae. It is dedicated to naturalist Alfred Grandidier (1836-1921).{{Cite journal|last=Baillon|date=1880|journal=Bull. Mens; Société Linnéenne de Paris|volume=1|pages=258}}

Species of Didierea are dioecious, with male and female flowers on separate plants.{{cite journal|doi=10.1007/BF01089291|title=Phylogeny of the Madagascan endemic family Didiereaceae|year=2000|last1=Applequist|first1=W.

They are listed in CITES appendix II, which means that their trade is restricted to protect natural populations.
