Polygonia undina is a butterfly of the family Nymphalidae first described by Grigory Grum-Grshimailo in 1890.

It is found from Ghissar-Darvaz to the Pamirs-Alai and Tian-Shan in north-western China and the Himalayas.

[1] It was treated as a subspecies of Polygonia egea, but DNA analysis concluded it deserves species status.
