Bothrops barnetti (Barnett's lancehead, Barnett's pit viper) is a venomous pitviper species endemic to Peru. No subspecies are currently recognized.
The specific name, barnetti, is in honor of Burgess Barnett (1888–1944), who collected the holotype and paratypes. Dr. Barnett was Curator of Reptiles at the London Zoo (1932–1937) and Superintendent of the Rangoon Zoological Gardens (1938–1944).
Bothrops barnetti is patterned in white and black triangles. Males usually grow to 120 cm (47 inches) in total length (including tail), whereas females are quite smaller and thinner. The body is heavily shaped and stocky.
English common names for B. barnetti are Barnett's lancehead and Barnett's pit viper. In Peru it is referred to as cascabel, cascabel falso, macanch, sancarranca, and zancarranca.
B. barnetti is found along the Pacific coast of northern Peru. It occurs at low elevations in arid, tropical scrub.
The type locality given is "from the mouths of Quebradas Honda and Perines, between Lobitos and Talara, northern Peru".
