The Oxalidales are an order of flowering plants, included within the rosid subgroup of dicotyledons. The following families are typically placed here:

  • Family Oxalidaceae (wood sorrel family)
  • Family Connaraceae
  • Family Elaeocarpaceae
  • Family Cunoniaceae
  • Family Cephalotaceae
  • Family Brunelliaceae

Under the older Cronquist system, most of the above families were placed in the Rosales. The Oxalidaceae were placed in the Geraniales, and the Elaeocarpaceae split between the Malvales and Polygalales, in the latter case being treated as the Tremandraceae.
