Nymphalis, commonly known as the tortoiseshells or anglewing butterflies, is a genus of brush-footed butterflies. The genera Aglais, Inachis, Polygonia and Kaniska, were sometimes included as subgenera of Nymphalis but they may instead be treated as distinct genera. See also anglewing butterflies. For other butterflies named tortoiseshells, see the genus Aglais.

Nymphalis, commonly known as the tortoiseshells or anglewing butterflies, is a genus of brush-footed butterflies. The genera Aglais, Inachis, Polygonia and Kaniska, were sometimes included as subgenera of Nymphalis but they may instead be treated as distinct genera. See also anglewing butterflies. For other butterflies named tortoiseshells, see the genus Aglais.
The name Nymphalis, established by Jan Krzysztof Kluk in 1780, is the oldest name among the generic names for a relatively small group of butterflies collectively known as anglewing butterflies. In zoological nomenclature, the oldest name has a priority over other names. The collective name anglewing butterflies is derived from a Latinised term Papiliones angulati. This name was probably used for the first time by Ignaz Schiffermüller in 1775–1776. The anglewing butterflies as a group are characterized by a cryptic silhouette and by the colouration and pattern on the ventral side of both wings. This signature mark is an important taxonomic characteristic as well as a significant evolutionary adaptation.
