We present a list of the anuran amphibians from “restinga” of Grumari, part of the Parque Natural Municipal de Grumari (PNMG), Rio de Janeiro municipality, state of Rio de Janeiro, southeastern Brazil. This study was carried out from May 2009 to December 2010 using two active sampling methods: quadrant plots and acoustic/visual transects. We recorded 22 anuran species distributed in six families: Bufonidae (1 species), Craugastoridae (1), Hylidae (14), Leptodactylidae (3), Microhylidae (2) and Strabomantidae (1). The presence of endangered and endemic species evidence Grumari’s importance as an area for conservation of the “restinga” habitat remnants in Rio de Janeiro. Grumari is also one of the richest known areas in terms of amphibian species among the “restinga” areas studied to date in Brazil, second only to Mata de São João, Bahia.
