'''Triuridales''' was an [[Order (biology)|order]] of [[angiosperm|flowering plants]] that was used in the [[Cronquist system]], in the subclass [[Alismatidae]].<ref>{{Citation |last=Johri |first=Brij M. |title=Triuridales |date=1992 |url=https://doi.org/10.1007/978-3-642-76395-3_53 |work=Comparative Embryology of Angiosperms: Vol. 1, 2 |pages=860–862 |editor-last=Johri |editor-first=Brij M. |access-date=2023-03-12 |place=Berlin, Heidelberg |publisher=Springer |language=en |doi=10.1007/978-3-642-76395-3_53 |isbn=978-3-642-76395-3 |last2=Ambegaokar |first2=Kunda B. |last3=Srivastava |first3=Prem S. |editor2-last=Ambegaokar |editor2-first=Kunda B. |editor3-last=Srivastava |editor3-first=Prem S.}}</ref> It used the folliwing circumscription:
* order Triuridales
*: family [[Petrosaviaceae]]
*: family [[Triuridaceae]]
In the classification system of [[Rolf Dahlgren|Dahlgren]] the Triuridales contained the single family Triuridaceae and was the sole order in the [[superorder]] Triuridiflorae (also called Triuridanae).
The [[APG II system]] leaves the first of these two families unassigned in the clade [[monocots]] while the second is moved to order [[Pandanales]]. In the [[APG III system|APG III]] and [[APG IV system]]s the second is placed in the monotypic order [[Petrosaviales]].
