Onthophagus nuchicornis is a species of dung beetle in the family Scarabaeidae.

It is found in Europe and North America.

[1][2][3] Though Onthophagus nuchicornis is listed as "Vulnerable" in the United Kingdom,[4] it is a common and abundant species in North America.

[5][6] It has been used as a model organism for ecotoxicological studies of ivermectin, where different biological endpoints (e.g. dung burial) are stimulated at low levels of ivermectin exposure, but impaired at high levels of ivermectin exposure.
