The Rhamnales are an order of dicotyledons. In the Cronquist system, the following families were placed here:

  • Family Rhamnaceae (buckthorn family)
  • Family Leeaceae
  • Family Vitaceae (grape family)

Leea may be included within the Vitaceae. The Rhamnaceae are no longer considered close relatives of these other forms, and newer systems move them to the Rosales. The order then becomes the Vitales.
