We provide a floristic and taxonomic treatment of Ficus sect. Americanae for the Brazilian state of Acre. The section is represented in Acre by 30 species. Ficus dugandii and F. pastasana are reported from Brazil for the first time. We reestablish several species, among them F. regularis (previously considered a synonym of F. trigona) and F. mathewsii and F. subapiculata (both previously considered subspecies of F. americana). Ficus acreana is treated here as a synonym of F. panurensis. We designate lectotypes for F. obtusifolia, F. pallida, and F. ypsilophlebia.
