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.

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.
