Dendropsophus decipiens is a species of frog in the family Hylidae. It is endemic to eastern Brazil between the Pernambuco and Rio de Janeiro states,^[2] or following IUCN, between the Maranhão and São Paulo states.^[1] It is also known as Brazilian coastal treefrog.^[2]

Dendropsophus decipiens is a very common species occurring in a wide range of habitats, such as open areas (pastures, grassland, and savanna), primary and secondary forests, and coastal restinga scrubland, at elevations up to 1,000 m (3,300 ft) above sea level. Typically, it is found on vegetation near water. The eggs are laid on tree leaves above bodies of water (both temporary and permanent); the tadpoles fall into the water where they continue to develop.^[1] It is a very adaptable species that does not face any known threats and that occurs in many protected areas.^[1]
