Desfontainia is a genus of flowering plants in the family Columelliaceae, though it was placed formerly in Loganiaceae, Potaliaceae (later subsumed in Gentianaceae), or a family of its own, Desfontainiaceae.
The genus was named for the French botanist, René Louiche Desfontaines. It is hardy to −5 °C (23 °F), and requires winter protection in areas with significant frosts.
