Prairie dogs are small stout-bodied burrowing rodents with shallow cheek pouches native to both North and Central America.

In 2003 they came to public attention in the U.S because pet prairie dogs spread monkeypox, a mild variant of smallpox previously unknown in North America, to more than a dozen people. The prairie dogs apparently contracted the disease from a Gambian pouched rat in a Chicago-area pet store.

An average size is 12 to 16 inches (30 to 40 cm) long. In the United States prairie dogs are primarily found west of the Mississippi River, but they have been introduced into a few eastern locales. All are herbivores, and in settled regions they sometimes damage crops severely.

An alternative classification treats the Sciurinae, including Cynomys as a Subfamily of the Sciuridae.
