Bothrops brazili (Brazil's lancehead) is a venomous pitviper species endemic to South America.

[3] The specific name, brazili, is in honor of Dr. Vital Brazil, a Brazilian physician and founder of the Instituto Butantan in São Paulo.

The rostral scale and lower edges of the supralabials are paler still, while a poorly defined postocular stripe may be present, running from the eye to the angle of the mouth, pale brown in color and bordered below by a dark brown line.

The type locality given is "Tomé Assú, Acará Mirim River, State of Pará, Brazil".

[5] As variations in scalation and color pattern are apparent in different populations of B. brazili, new taxa will likely be defined as a result of further research.
