Faunis eumeus, the large faun,[1] is a butterfly found in South and South East Asia that belongs to the Morphinae subfamily of the brush-footed butterfly family.

[1][2] The large faun ranges from Assam to the Shan States and Burma.

Underside maroon brown; apex of forewing broadly paler, dorsal margin of same dull brown; subbasal, discal and postdiscal dark, sinuous, continuous lines crossing both wings; between the latter two a series of prominent round white spots, five or six on the forewing (straight in the male, slightly incurved in the female), six or seven on the hindwing, arched in both sexes.

[3] The subspecies incerta from the Shan States is reported by William Harry Evans as very rare.
