Fothergilla malloryi is an extinct species of flowering plant in the family Hamamelidaceae known from fossil leaves found in the early Eocene[1] Klondike Mountain Formation deposits of northern Washington state.

[2] The F. malloryi leaves are the earliest appearance in the fossil record of a member of the witchalder genus Fothergilla, which includes the living species F. gardenii, and F. major, both of which are native to the southeastern United States.

Fothergilla durhamensis described from Eocene sediments in King County, Washington is considered dubious in placement,[2] and it was transferred to the genus Platimeliphyllum by Huegele et al.

[3] Fothergilla malloryi is represented by a single counterpart compression fossil specimen from the Ypresian[1] aged Klondike Mountain Formation which outcrops in Republic, Ferry County, Washington.

[2] The specimen was studied by paleobotanists Meghan G. Radtke and Kathleen B. Pigg of the School of Life Sciences, Arizona State University and Wesley C. Wehr of the Burke Museum of Natural History and Culture in Seattle.
