Melanargia is a genus of butterflies belonging to the family Nymphalidae and the subfamily Satyrinae (formerly family Satyridae).

This genus, described by Johann Wilhelm Meigen in 1828, is the only genus in the subtribe Melanargiina, Wheeler, 1903.

The adults of this genus of satyrines are easily distinguished by their white wings with black veins and markings (hence the common name "marbled whites"). A peculiar phenotypic distinctiveness is also a dilated vein 12 at the base of the forewing.

Butterflies of genus Melanargia are widespread from Europe and north Africa to Japan.
