Bothrops otavioi, also known as Jararaca-de-Vitória in Portuguese, is an endangered species of pit viper from Vitória Island, São Paulo, Brazil.

The species is named after Otavio A. V. Marques, a prominent herpetologist at the Instituto Butantan.

[1] B. otavioi can also be distinguished from B. alcatraz by its fewer intersupraoculars, more ventrals, more subcaudals in males as well as its longer tail and head.

It can also be distinguished from B. insularis by its brown colours, fewer intersupraoculars and anterior cephalic scales as well as its smaller males.

[1] Bothrops otavioi is arboreal and nocturnal, it is also known to eat small hylid frogs.
