Hypericum russeggeri is a species of flowering plant in the St John's wort family Hypericaceae. The plant is a small shrub with many branches that spread across the ground, and it has many small flowers with pale yellow petals. It is found only among calcareous rocks along the coast and in the foothills of the Nur Mountains of eastern Turkey and northern Syria. While H. russeggeri has an array of phytochemicals present in its flowering structures and leaves, these are found in lower concentrations than other species of Hypericum. The species was first described in 1842 as Triadenia russeggeri, and it has been placed into various defunct genera including Elodea and Adenotrias. It is now known as Hypericum russeggeri and is the type species of Hypericum section Adenotrias, a small section that also includes H. aegypticum and H. aciferum.
