Sullivantia, commonly called coolwort,[1] is a genus of flowering plants in the saxifrage family.

It is a small genus, comprising only 3-4 species of perennial herbs all native to the northwestern and east-central United States.

Sullivantia is most notable for having disjunct distributions primarily restricted to along the Pleistocene glacial margin.

[2] All species of Sullivantia are found on moist, often calcareous cliffs.
