This study provides an annotated list of the species of Pitcairnioideae (Bromeliaceae) from Lambayeque, Peru. A total of five species are reported, one of them for the first time for the study area and two represent northern Peruvian endemisms. The ecoregions where they are found correspond to the Tropical Warm Desert (DCT), Seasonal Dry Forest (BSe), the Desert Scrub-Dry Forest transition (MD-BS) and the Northwest Montane Pluvial Forest (MNPF), in the three provinces of the department. The reasons for endemism, threats and criteria for their categorization are discussed.
