Austrobaileyales is the botanical name for an order of flowering plants, consisting of about 100cite journal | url = http://www.amjbot.org/cgi/content/full/91/10/1437 | title = The plant tree of life: an overview and some points of view | author = Jeffrey D.

In different classifications

Until the early 21st century, the order was only rarely recognised by systems of classification (an exception is the Reveal system).

The APG system, of 1998, did not recognize such an order. The APG II system, of 2003, does accept this order and places it among the basal angiosperms, that is: it does not belong to any further clade. APG II uses this circumscription:

* order Austrobaileyales
** family Austrobaileyaceae, two species of woody vines from Australia
** family Schisandraceae [+ family Illiciaceae] , several dozen species of woody plants, found in tropical to temperate regions of East and Southeast Asia and the Caribbean.
** family Trimeniaceae, half-a-dozen species, of woody plants found in subtropical to tropical Southeast Asia, eastern Australia and the Pacific Islands

Note: "+ ..." = optional seggregrate family, that may be split off from the preceding family. The Cronquist system, of 1981, also placed the plants in families Illiciaceae and Schisandraceae together, but as separate families, united at the rank of order, in the order Illiciales.

The current phylogeny is:
