Helianthemum (/ˌhliˈænθɪməm/), known as rock rose, sunrose, rushrose, or frostweed, is a genus of about 110 species of flowering plants in the family Cistaceae. They are widely distributed throughout the Northern Hemisphere, especially in the Mediterranean.

New World species formerly classified as Helianthemum have been transferred to genus Crocanthemum.
