Polyura jupiter is a butterfly of the family Nymphalidae.

It is found in Indonesia and surrounding islands.

The upper side is brown, very largely marked with white, with forewings in a triangle from the costal margin and in the form of spots, including small ones in a submarginal line, and on the hindwings in a broad triangle, from the costal edge to the anal angle marked by an orange spot.

Walter Rothschild and Karl Jordan (1900) provide a full description.
