Petrorhagia dubia is a species of flowering plant in the family Caryophyllaceae known by the common name hairy pink.

[2] It is native to southern Europe and the Mediterranean Basin, but it is known on other continents, including Australia and North and South America, as an introduced species and sometimes a weed.

The inflorescence bears a head-like cluster of flowers, their bases enclosed in a large, expanded mass of wide, claw-tipped bracts.

The flower corollas are each further encased in a tubular calyx of sepals.

The petals are bright pink to magenta or lavender in color with darker veins.
