Estevia is a genus of fossil formicine ants containg two species known from Fushun amber. It was originally described in 2002 by Chinese paleoentomologist Youchong Hong () as Wilsonia, an honorific of biologist E. O. Wilson, however entomologist Brian Fisher found that the name was a junior secondary homonym of the bird genus Wilsonia described in 1838 and designated Estevia as a replacement name in 2026 in honor of Brazilian myrmecologist Flávia Esteves.
As of 2026, the genus includes one species officially designated within the genus and one implied.
