The Walnut Sphinx (Amorpha juglandis) is a moth of the Sphingidae family. It lives from the Atlantic Ocean to the Rocky Mountains and from the southern United States up into parts of Canada.

The wingspan is 45-75 mm. Adult moths are nocturnal, being found rarely outside the early hours of the night.

The caterpillars feed on Alder (Alnus), Hickory (Carya), Hazelnut (Corylus), Beech (Fagus), Walnut (Juglans) and Hop-hornbeam (Ostrya) species.
