The Dilleniales are an order of flowering plants, potentially containing one family, Dilleniaceae.

[1] Stevens at the Angiosperm Phylogeny Website has subsequently placed Dilleniaceae in the order Dilleniales.

[2] The Cronquist system, of 1981, recognized such an order and placed it in subclass Dilleniidae.

It used the following circumscription:[citation needed] The Takhtajan system of 1969 had the families Dilleniaceae and Crossosomataceae in the order.

[citation needed] The APG III system assigned the second of these families, the Paeoniaceae, to the order Saxifragales.
