Proceratophrys boiei, commonly known as Boie's frog, is a species of frog in the family Odontophrynidae. It is endemic to eastern and southeastern Brazil. This common frog is found in primary and secondary forest, on the forest edge, and in degraded areas near forest. This species is present in the illegal pet trade. Its habitat is subject to loss caused by agriculture, wood plantations, livestock grazing, clear-cutting, human settlement and tourism. The specific name boiei was given in honour of German zoologist Heinrich Boie or his brother Friedrich Boie.
Proceratophrys boiei is a moderate-sized, robust frog, growing to a length of between 40 and 70 mm (1.6 and 2.8 in), with males tending to be slightly smaller than females. Both head and body are relatively broad, the snout is rounded, and long, tapering peaks of skin project from above the eyes. The surface of the skin on both back and flanks is covered with warts. The colouring is an irregular geometric pattern of brown, black, yellow, orange and red, such that the frog becomes nearly invisible against the background of leaf litter among which it lives. There is also a broad brown or grey dorsal stripe.

GBIF citizen-science records
It is estimated from how often the Boie's Frog is recorded against all the amphibians logged in Serra dos Órgãos National Park (6 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
