Physalaemus soaresi is a species of frog in the family Leptodactylidae.

It is endemic to southeastern Brazil where it is only known from three localities in the Rio de Janeiro state,[2] one of them lost to urbanization and habitat degradation.

[3] The existing populations occur in secondary forest habitats, one of them very close to sea level, another one at 130 m (430 ft) above sea level.

Both locations suffer from habitat loss, and the latter also from fire.

[1][3] The species lays its eggs in a foam nest on the surface of temporary pools.
