Paeonia parnassica, the Greek peony, is a flowering plant in the Paeoniaceae family.

It is native to the mountains of south-central Greece.

The flowers are produced in late spring with a deep maroon red colouring on 65 cm stems.

The blooms are large, up to 12 cm in diameter and bear a boss of rich orange stamens.

[2] The Greek peony is an autotetraploid (4n=20) of which the diploid parent must have gone extinct.
