Pocket gophers weigh around {{convert|1/2|lb|g|order=flip|sigfig=1|abbr=on}}, and are about {{convert|6-8|in|cm|order=flip|abbr=on}} in body length, with a tail {{convert|1-2|in|cm|order=flip|round=0.5|abbr=on}} long. A few species reach weights approaching {{convert|1|kg|abbr=on}}. Within any particular gopher species, the males are larger than the females, and can be nearly double their weight.{{cite book

Most gophers have brown fur that often closely matches the color of the soil in which they live. Their most characteristic features are their large cheek pouches, from which the word "pocket" in their name derives. These pouches are fur-lined, can be turned inside out, and extend from the side of the mouth well back onto the shoulders. Gophers have small eyes and a short, hairy tail, which they use to feel around tunnels when they walk backwards.

Pocket gophers have often been found to carry external parasites including, most commonly, lice, but also ticks, fleas, and mites. Common predators of the gopher include weasels, snakes, and hawks.{{cite web | url=http://www.nwf.org/wildlife/wildlife-library/mammals/pocket-gophers.aspx | title=Pocket Gophers | publisher=National Wildlife Federation | access-date=19 January 2014}}

All pocket gophers create a network of tunnel systems that provide protection and a means of collecting food. They are larder hoarders, and their cheek pouches are used for transporting food back to their burrows. Gophers can collect large hoards. Unlike ground squirrels, gophers do not live in large communities and seldom find themselves above ground. Tunnel entrances can be identified by small piles of loose soil covering the opening.{{cite web | url=http://a-z-animals.com/animals/gopher | title=Gopher | publisher=A-Z Animals | access-date=19 January 2014}} Burrows are in many areas where the soil is softer and easily tunneled. Gophers often visit vegetable gardens, lawns, or farms, as they like moist soil (see Soil biomantle). This has led to their frequent treatment as pests.

Gophers eat plant roots, shrubs, and other vegetables such as carrots, lettuce, radishes, and any other vegetables with juice.{{cite web|title=Pocket Gopher FAQs|url=http://gophergetter.us/faq/|access-date=2 February 2018|archive-date=3 February 2018|archive-url=https://web.archive.org/web/20180203064635/http://gophergetter.us/faq/|url-status=dead}} Some species are considered agricultural pests. The resulting destruction of plant life then leaves the area a stretch of denuded soil. At the same time, the soil disturbance created by turning it over can lead to the early establishment of ecological succession in communities of r-selected and other ruderal plant species. The stashing and subsequent decomposition of plant material in the gophers' larder can produce deep fertilization of the soil.

Pocket gophers are solitary outside of the breeding season, aggressively maintaining territories that vary in size depending on the resources available. Males and females may share some burrows and nesting chambers if their territories border each other, but in general, each pocket gopher inhabits its own individual tunnel system. Although they attempt to flee when threatened, they may attack other animals, including cats and humans, and can inflict serious bites with their long, sharp teeth.

Depending on the species and local conditions, pocket gophers may have a specific annual breeding season, or may breed repeatedly through the year. Each litter typically consists of two to five young, although this may be much higher in some species. The young are born blind and helpless and are weaned when around 40 days old.{{cite book|editor= Macdonald, D.|author= Patton, James|year= 1984|title= The Encyclopedia of Mammals|publisher= Facts on File|location= New York|pages= [https://archive.org/details/encyclopediaofma00mals_0/page/628 628–631]|isbn= 0-87196-871-1|url-access= registration|url= https://archive.org/details/encyclopediaofma00mals_0/page/628}}

Much debate exists among taxonomists about which races of pocket gophers should be recognized as full species, and the following list cannot be regarded as definitive.
