The Red-fringed Emerald or Two-striped Emerald (Nemoria bistriaria) is a species of moth of the Geometridae family. It is found from New Brunswick to Florida, west to Texas, north to Ontario.

The wingspan is about 22 mm. Adults are on wing from March to October in the south and from May to August in the north. There are at least two generations per year.

The species occurs in a seasonal brown form where the green colour of the wings is entirely replaced by a light coffee colour.
