Human zoos, also called ethnological expositions, were 19th-, 20th-, and 21st-century public exhibitions of humans, usually in a so-called natural or primitive state.

The displays often emphasized the cultural differences between Europeans of Western civilization and non-European peoples or with other Europeans who practiced a lifestyle deemed more primitive. Some of them placed indigenous populations in a continuum somewhere between the great apes and Europeans.

Ethnological expositions are sometimes criticized and ascertained as highly degrading and racist, depending on the show and individuals involved.
