Hunnemannia is a monotypic genus of flowering plants in the poppy family Papaveraceae, containing the single species Hunnemannia fumariifolia (tulip poppy or Mexican tulip poppy) native to the highlands of Mexico. It is typically found at elevations of 1,500–2,000 m (4,921–6,562 ft) in the Chihuahuan Desert and south into central Mexico, where it favors rocky habitats, occurring along roadsides as well. The genus is named for English botanist and collector John Hunnemann (1760-1839). The Latin fumariifolia literally means "with leaves like Fumaria" (fumitory).
