Dyckia is a genus of plants in the family Bromeliaceae, subfamily Pitcairnioideae.

The genus is named after the Prussian botanist, botanical artist and horticulturist The Prince and Earl of Salm Reifferscheid-Dyck (1773–1861).

Dyckias, with stiff and thorny leaves, prefer rocky and/or sunny areas and have a natural tendency to clump leading to thick, large mats.

The subfamily Pitcairnioideae contains several "terrestrial" members of the Bromeliaceae, with cultivated genera including Dyckia, Hechtia, Pitcairnia and Puya. They are endemic to arid and high-altitude regions of Brazil and the central part of South America.
