Ginkgo adiantoides is a species of Ginkgo that first appears in the Late Cretaceous where it can be found in much of Asia and Western North America. It would then survive the end-Cretaceous extinction event and continue to be an important plant long into the Cenozoic.

Unlike the lobed leaves of other ginkgoes, G. adiantoides is characterized by wide, rounded leaves resembling a Japanese folding fan. It now also bares only a single seed per stalk, like the modern Ginkgo biloba. It has been suggested that G. adiantoides is likely the direct ancestor of the modern species.

This species inhabited disturbed streamside and levee environments in the Late Cretaceous to Miocene. This was also one of the environments first to be invaded by flowering plants, which may have displaced Ginkgo from its natural habitat, eventually confining it to just a few isolated pockets in the mountains of China.
