The pocket gophers are burrowing rodents of the family Geomyidae. These are the "true" gophers. Several ground squirrels of the family Sciuridae are often called gophers as well. They are not true gophers,though. The name "pocket gopher" on its own is used for a number of subspecies of the family. Pocket gophers, despite being largely a pest, are a symbol of the U.S. state of Minnesota, sometimes called "the Gopher State". They are a pest and are killed with dry ice.
