Chiasmocleis bicegoi, the Cecilia humming frog or Santa Cecilia humming frog, is a frog in the family Microhylidae.

It is endemic to Brazil.

Scientists have only collected it with certainty from its type locality, but they believe it to be more widespread.

[1][2] Scientists used to consider this frog part of Chiasmocleis albopunctata, but it was placed in its own taxon in 2018.
