Kerpia macroloba is a fossil taxa of Ginkgo found in the Ural region of western Russia, dating from the Kungurian stage of the Early Permian Period (272 mya). The taxa was named by S. V. Naugolnykh. It belongs to the class of gymnosperms, the divisison Ginkgophyta, and the order Ginkgoales.

While the fossil record shows that a number of different Ginkgo taxa existed in the Permian, today only a single genus survivies, Ginkgo biloba, an evergreen tree which represents a kind of living fossil.
