Billbergia is a genus of flowering plants in the family Bromeliaceae, subfamily Bromelioideae. The genus, named for the Swedish botanist, zoologist, and anatomist Gustaf Johan Billberg, is divided into two subgenera: Billbergia and Helicodea. They are native to forest and scrub, up to an altitude of 1,700 m (5,577 ft), in southern Mexico, the West Indies, Central America and South America, with many species endemic to Brazil. They are rosette-forming, evergreen perennials, usually epiphytic in habit, often with brilliantly coloured flowers.
