The Polygalaceae or the milkwort family are made up of flowering plants in the order Fabales. They have a near-cosmopolitan range, with about 27 genera and ca. 900 known species[2] of herbs, shrubs and trees. Over half of the species are in one genus, Polygala, the milkworts.

The family was first described in 1809 by Johann Hoffmansegg and Johann Link.[3] In 1896, Robert Chodat split it into 3 tribes. A fourth tribe was split off from the tribe Polygaleae in 1992.[4] Under the Cronquist classification system, Polygalaceae were treated in a separate order of their own, Polygalales. Currently, according to the Angiosperm Phylogeny Group, the family belongs in Fabales.
