Primatology is the scientific study of primates. Unlike branches of zoology focused on specific animal groups (such as ornithology, the study of birds), primatology – and the primate order — includes both human and nonhuman animals. Thus, the field entails significant overlap with anthropology, the study of humans, and related sciences.

Primatology encompasses a broad swath of scientists from different fields of study, each with distinct perspectives. For example, behavioral ecologists may focus on ways primate species act in different environments or circumstances. Sociobiologists are concerned with genetic inheritance and primates' physical and behavioral traits. Anthropologists tend to focus on humans' evolutionary history; they look to primates for greater insights into how Homo Sapiens have evolved. Comparative psychologists study differences between human and nonhuman primate minds.

Some primatologists work in the field to study animals in their natural environments; others work in academia in labs conducting experiments. Many do a mix of both. In the 21st century, primatologists have often blended approaches, incorporating both experimentation and observational data to varying degrees.

Many primatologists work outside of academia. In places where nonhuman primates are indigenous — Asia, Africa, and South America — they often work in government to balance human-wildlife coexistence and promote conservation. Primatologists also work in animal sanctuaries, NGOs, biomedical research facilities, museums and zoos.

Primatology was established as a discipline in the 1950s in America/Europe and in Japan. (See History below.) International programs — in South America, Africa, and other parts of Asia — began taking off in the 1970s.

Given the wide variety of disciplines involving primates, some specialists speak of primatology not as a single discipline but of multidisciplinary "primatologies." Primatology in the U.S. largely originated with anthropology and its strong bent toward understanding humans and defining human uniqueness. In contrast, "establishing the human-animal divide is generally of little importance to non-Western primatologies."

Researchers from Brazil, India, Vietnam, Africa and areas with indigenous primates have adopted many Western practices while focusing on objectives and approaches that reflect local challenges and cultural traditions. Human populations in these countries have different relationships and experiences with wild primates than do those in the West. The human-primate "interface" (the scientific term for human-nonhuman interactions) is thus a key point of research. Population dynamics, with repeated conservation surveys, form a significant part of research activities for Indian primatologists, for example. Primate rescue centers are key research hubs in Vietnam. Ecology, demography, human-wildlife conflict, and conservation of interconnected species and ecosystems are all possible focal points.

Ethnoprimatology is a 21st-century subdiscipline focused on the social, cultural, and ecological contexts of human-primate interactions. (These interactions have also been viewed as human-wildlife conflict and human-wildlife coexistence.) As habitat loss continues to worsen internationally, primatologists Agustin Fuentes and Kimberley J. Hockings state that understanding which primates are best able to adapt and interface with human populations, and how they are able to do so, is a new frontier for primatology.
