The Serra dos Órgãos National Park (PARNASO) is located in montane region of Rio de Janeiro state and is an important Brazilian protected area, preserving important ecosystems of the Atlantic Forest of southeastern Brazil. Here we present a taxonomic study of the genera Edmundoa, Neoregelia and Wittrockia (Bromeliaceae, Bromelioideae) in PARNASO, based on field collections, herbarium material and bibliography. Descriptions were made based on the morphological variations observed in all specimens from the region. Sixteen taxa were found, being Neoregelia the richest genus with 13 species, followed by Wittrockia (two) and Edmundoa (one), none of them is included in official lists of endangered species. Identification keys, descriptions, information on geographic distribution and morphological and taxonomical comments for taxa are presented.
