Lamourouxia is a genus of flowering plants belonging to the family Orobanchaceae.

[1] Its native range is Mexico to Peru.

It is found in the countries of Belize, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panamá and Peru.

[1] Kew also adds Magadan in Russia,[1] this could be a random mistake.

The genus name of Lamourouxia is in honour of Jean Vincent Félix Lamouroux (1779–1825), a French biologist and naturalist, noted for his seminal work with algae.
