Aglais is a Holarctic genus of brush-footed butterflies, containing the tortoiseshells.

This genus is sometimes indicated as a subgenus of Nymphalis or simply being an unnecessary division from the genus Nymphalis,[1][2][3] which also includes tortoiseshells, but it is usually considered to be separate.

[4] This proposed separate genus is also considered "brushfooted butterflies" historically together with the other or separate Nymphalis species.
