Karkenia Archangelsky, 1965 Karkeniaceae is an extinct family in the order Ginkgoales.

It is distinguished by "Ovulate organs consisting of a peduncle and helically arranged, up to about 100 small, orthotropous but incurved ovules; pedicel present; nucellus largely free."

Unlike other ginkgoales, the seeds are borne on cone-like aggregations.

Ovuluate organs of Karkenia are associated with leaves of the Ginkgoites, Sphenobaiera and Eretmophyllum types.
