Eurema lisa, commonly known as the little yellow, little sulphur or little sulfur, is a butterfly species of subfamily Coliadinae that occurs in Central America and the southern part of North America.

The little yellow lives as far south as Costa Rica north through southern portions of the United States, they can be seen throughout much more of the United States but this is due to seasonal colonization from the south.

During warm days males patrol for females so they can mate.

Females lay eggs singly on the midveins of their host plant.

The adults feed on the nectar of species in the genus Aster.
