Stigmella is a genus of moths of the family Nepticulidae.

The genus was erected by Franz von Paula Schrank in 1802.

Stigmella is a species-rich genus of tiny moths belonging to the family Nepticulidae, which contains the smallest moths, with a wingspan of only 2.5 mm.

Most of the dwarf moths have larvae that mine (eat the contents of the plant without breaking the surface) in the leaves of various plants, but there are also some that live in seeds or bark.

Adults must be reared and/or determined by microscopic examination of the genitalia.
