Illiciaceae A.C.Sm. was a family of flowering plants recognized in a number of systems of plant taxonomy. The Illiciaceae is not recognized as a distinct family by the APG III system of plant taxonomy, the most well accepted system in use today.

The APG II system treated Illiciaceae as a family that may either be treated as part of another family, the Schisandraceae or allows for the optional segregation of the Illiciaceae from the Schisandraceae. The Illiciaceae as an optional segregate family then has the traditional circumscription of other taxonomic systems, consisting of a single genus, Illicium. The updated APG III system of 2009 does not recognize this family and includes Illicium in the Schisandraceae.
