Adonis pyrenaica, common name Pyrenean pheasant's eye, is a species of plant in the family Ranunculaceae.

This very rare species is a native plant of the Pyrenees and the Cantabrian Mountains in southwestern Europe.

These orophyte plants prefer rocky mountains, with calcareous or sometimes siliceous scree and stony lawns with discontinuous vegetation, at an elevation of 1,300–2,400 metres (4,300–7,900 ft) above sea level.

[4] Adonis pyrenaica has an erect and a little pubescent stem, forming thick tufts measuring approximately 10–30 centimetres (3.9–11.8 in).

It blooms from June to July and it is pollinated by insects (entomophily), where as seeds are disseminated by the animals.
