The Polygalaceae (syn. Diclidantheraceae, Moutabeaceae, Xanthophyllaceae) or the milkwort family are made up of flowering plants in the order Fabales. They have a near-cosmopolitan range, with about 21 genera and ca 900 known species[2] of herbs, shrubs and trees. Over half of the species are in one genus, Polygala, the milkworts.

Under the Cronquist classification system, Polygalaceae were treated in a separate order of their own, Polygalales. Currently, according to the APG, the family belongs in Fabales.
