Corylopsis reedae 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] Corylopsis reedae is represented by a single counterpart compression fossil specimen from the Ypresian-aged[1] Klondike Mountain Formation that outcrops in Republic, Ferry County, Washington.

[2] The fossil was recovered from the "Corner lot", University of Washington site UWBM A0307, located within the city limits of Republic.

[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.

The etymology of the specific name readae was derived from Katherine ("Kitty") M. Reed in honor of her contributions to the Tertiary stratigraphy and paleontology of the Pacific northwest.
