Stigmella saginella is a moth of the Nepticulidae family. It is found in North America in Ohio, New York, Virginia, Massachusetts, Illinois, Missouri, Pennsylvania, Kentucky, California, Ontario and Quebec. The wingspan is 4-5.5 mm. The larvae feed on Quercus species, including Q. prinus, Q. platanoides and Q. alba. They mine the leaves of their host plant.

The larvae are bright green and the cocoon is usually whitish but occasionally ochraceous.
