The Hamemelidales are an order of dicotyledons in the Cronquist system, including the following families:

  • Family Hamamelidaceae (witch hazel family)
  • Family Cercidiphyllaceae (katsura tree)
  • Family Eupteleaceae
  • Family Platanaceae (plane trees)
  • Family Myrothamnaceae (resurrection bush)

These served as the prototype for the subclass Hamamelidae. In newer classifications, these families are scattered among various other orders of dicots, most notably the Saxifragales.
