Asphodelaceae is a family of flowering plants in the order Asparagales. Until 2016, the name Xanthorrhoeaceae was used for the family in the APG classification system. Such a family has been recognized by most taxonomists, but the circumscription has varied widely. In its current circumscription in the APG IV system, it includes about 40 genera and 900 known species.
As defined by the Angiosperm Phylogeny Group in 2009 (the APG III system), the family consisted of three subfamilies: Asphodeloideae, Hemerocallidoideae and Xanthorrhoeoideae. Earlier these three had been treated as separate families. The family Asphodelaceae has now been proposed to be a nomen conservandum (conserved name), and the proposal has been recommended for ratification in 2017. In that case, Asphodelaceae will have priority over Xanthorrhoeaceae. This is reflected in the APG IV family lists.
The family has a wide, but scattered distribution throughout the tropics and temperate zones. Many of the species are cultivated as ornamentals. A few are grown commercially for cut flowers. Two species of Aloe are grown for their leaf sap, which has medicinal and cosmetic uses. Xanthorrhoea is endemic to Australia.
