Triuridales was an order of flower plants that was used in the Cronquist system, in the subclass Alismatidae, with this circumscription:
In the classification system of Dahlgren the Triuridales contained the single family Triuridaceae and was the sole order in the superorder Triuridiflorae.
The APG II system leaves the first of these two families unassigned in the clade monocots while the second is moved to order Pandanales. The name was a botanical name.
