Agriades orbitulus, the alpine argus, is a butterfly of the family Lycaenidae.

It is a high altitude species found in the Alps (ranging from the French Alps to Slovenia and Austria), the mountains of Norway and Sweden, the Urals, the Himalayas and across central Asia.

The female is brown, often with a slight blue dust suffusion at the wing bases.

Both sexes are clearly assigned by conspicuous white spots on the otherwise pale greyish brown or beige wing underside.

The spots under the hind-wing are pure white and lack black centres.
