'''Dioscoreaceae''' {{IPAc-en|d|eye|Q|,|s|k|ohr|i|'|ay|s|ee}} is a [[family]] of [[monocotyledon]]ous [[flowering plants]], with about 715 known [[species]] in nine [[genus|genera]].<ref name="Christenhusz-Byng2016">{{cite journal |author1=Christenhusz, M.

The [[APG system]] (1998) and [[APG II system]] (2003) both place it in the order [[Dioscoreales]], in the clade [[monocots]]. However, the circumscription changed in the APG II system, with the 2003 system expanded to include the plants that in the 1998 system were treated in the families '''Taccaceae''' and '''Trichopodaceae'''.

=== Subdivision ===
 
The [[circumscription (taxonomy)|circumscription]] of Dioscoreaceae has expanded over the years. For instance when Stenomeridaceae, as ''[[Stenomeris]]'' was also included in Dioscoreaceae as subfamily Stenomeridoideae together with ''Avetra'', the remaining four genera were grouped in [[subfamily]] Dioscoreoideae, the two being distinguished by the presence of bisexual and unisexual flowers respectively.{{sfn|Bouman|1995}}
