Kickxia is a genus of plants in the plantain family (Plantaginaceae).

It includes several species known commonly as cancerworts or fluellins.

Species are mostly native to Europe, Central Asia, and Africa,[2] with two, K. elatine and K. spuria, well-established as invasive elsewhere.

The genus Kickxia was named after the Belgian botanist Jean Kickx.
