Haloragaceae is a family in the order of Saxifragales, of dicotyledon flowering plants. In the Cronquist system, it was included in the order Haloragales, but in the APG II system, it is placed in Saxifragales.
The distribution of the family is nearly worldwide. The center of species diversity is in Australia and the Southern Hemisphere.
They are perennial, or occasionally annuals, and mostly leafy plants, although there are woody taxa. Some are land plants and others grow in freshwater. The plants are mainly monoecious and the flowers are nearly always small and radial. There is only one ovule per carpel. The ovaries are syncarp and epigynous.
In the family there are nine genera, with 145 species:
The taxa of the earlier family Cercodiaceae and Myriophyllaceae are now included in the family Haloragaceae. Earlier, the genus Gunnera was included in this family.
