Cistus crispus is a shrubby species of flowering plant in the family Cistaceae, with pink to purple flowers, native to south-western Europe and western north Africa.

Its grey-green leaves are wavy (undulate), oblong to elliptical in shape, usually 1–4 cm (0.4–1.6 in) long by 4–15 mm (0.2–0.6 in) wide.

[2] Cistus crispus was first described by Carl Linnaeus in 1753 in Species Plantarum (p. 524).

[1] The specific epithet crispus means "curly" or "finely waved", referring to the leaves.

[4] A 2011 molecular phylogenetic study placed C. crispus as the deepest branching member of the clade of purple and pink flowered Cistus species (the "purple pink clade" or PPC).
