Antigonon is a genus of flowering plants in the buckwheat family, Polygonaceae. It contains three species native to the Americas.

Their leaves are alternately arranged, with flowers borne in raceme-like clusters, often toward the ends of the stems. The bell-shaped flowers have five tepals usually in shades of pink or purplish, and sometimes yellowish or white. The stamens are joined at the bases, forming a tube.

• Antigonon flavescens S.Watson lovechain

• Antigonon guatimalense Meisn.

• Antigonon leptopus Hook. & Arn. Confederate vine, Mexican coral vine, Mexican creeper, queen's wreath, queen's jewels, chain-of-love, mountain rose coral vine
