The Hamamelidaceae is a family of flowering plants in the order Saxifragales, including 27 genera and about 80-90 species, all shrubs and small trees. In older classifications such as the Cronquist system, the family was treated in a separate order Hamamelidales.

;Genera
*"Chunia"
*"Corylopsis" (Winter-hazel; about 30 species; east Asia)
*"Dicoryphe"
*"Disanthus" (1 species; east Asia)
*"Distyliopsis"
*"Distylium" (about 10 species; east Asia, Himalayas)
*"Embolanthera"
*"Eustigma"
*"Exbucklandia" (1 species; southeast Asia)
*"Fortunearia" (1 species; eastern China)
*"Fothergilla" (Fothergilla; 3 species; southeastern U.S.)
*"Hamamelis" (Witch-hazel; 4 species; eastern North America, east Asia)
*"Loropetalum" (2 species; east Asia)
*"Maingaya"
*"Matudaea"
*"Molinadendron"
*"Mytilaria"
*"Neostrearia"
*"Noahdendron"
*"Ostrearia"
*"Parrotia" (Persian Ironwood; 1 species; Alborz Mountains of southwest Asia)
*"Parrotiopsis" (1 species; Himalaya)
*"Rhodoleia" (about 7 species; southeast Asia)
*"Sinowilsonia" (1 species; western China)
*"Sycopsis" (about 7 species; southeast Asia)
*"Tetrathyrium"
*"Trichocladus"

Some authors treat "Rhodoleia" in a family of its own, the Rhodoleiaceae, though genetic research by the Angiosperm Phylogeny Group shows it is best included in the Hamamelidaceae.

The genera "Altingia", "Liquidambar" (sweetgum) and "Semiliquidambar", previously included in the Hamamelidaceae, are now treated in the family Altingiaceae.
